    Help understanding graphics cards???

    Okay, i'm running a Pentium Quad Core Q8400 pc, with 4gb ram, 1tb hhd, and a 256 built in intel graphics card.

    I dont often play games, maybe the odd game of Team Fortress. I would LIKE to play something like Call of Duty or Crysis.

    I also enjoy converting movies from HD to DVD. Gaming is not a must.

    If i buy a graphics card e.g. Asus HD 4350 512MB DDR2 to replace the inbuilt one, what difference would this make on my systems performance?

    I cant purchase a high end graphics card as my power supply outputs 255w. Will buying a new graphics card increase the speed of video coding? will it help speed up dvd burning?

    Can someone recommend the highest graphics card i can get for my pc without havig to change my power supply?

    My mainboard is a FOXCONN G31MX, i know it's not probably the best of mainboards but i just want to know whats the best graphics card i can get for this to go with my powersupply and mainboard?

    It won't speed up dvd burning. I'd recommend a ATI or Nvidia graphics card.

    you will need a more powerful psu 500w or higher depends on what card you go for, whats your budget

    problem is i dont know which one would be compatible with my system? as ebuyer doesnt tell you the minimum power output that is required

    about £50??

    If i change the power supply, i'm lacking confidence on knowing where all the cables go again

    its got a PCI Express x16 so you can go for any nvidia or ati card

    you wont get much for £50, a decent psu will cost you about £50 at least
    then graphics are about £80 upwards

    If it's got pci express card x16 does that mean i can opt for any graphics card that uses pci e x 16?

    do you think i'd be able to use this card without changing power supplies

    If you are using your PC for video decoding/encoding and/or authoring DVDs then a high end graphics card will not improve things. Video encoding/decodeing involves converting from one format to another via mathematical algorithms. The graphics card has no purpose in this respect as it is the CPU that does the work. I see that you have a Quad Core CPU which most encoder/decoder software can take advantage of so there is not much more room for upgrade (other than Core i5/i7 processors, P55/X58 motherboards respectively).

    DVD authoring will not be impacted either by a graphics card upgrade. Some graphics cards support complex 3D modelling which is useful for CAD work and animation, gaming cards support hardware for rendering. You are simply using the processor and the DVD drive so there is no need to upgrade your graphics card.

    EDIT: Ah I see you wish to play Call of Duty and Crysis in which case you will need a gaming graphics card such as Radeon HD 5770. It is a mid range card but inexpensive and supports DX11.

    he wants to play some games, so wants to upgrade grahics

    Yes I believe so but your frame rates and resolution wont be anywhere near good quality.

    Yep I've just seen it and edited my post.

    Crysis is the most demanding game for any graphics card ,Call of duty isnt so bad but if you want to play these games then you will have to buy a PSU as well as a card,You have a choice you can either play these games and spend £100-£120 on a card and PSU or you can forget about these games and spend £40 -£50 on a card for basic use which will encoding video.But first you need to decide,

    Sorry to intrude OP but I have a graphics card related question myself, I currently have a HD4870 that I got last November but only used from July since my old one died and I love it but its a bit big for my matx case as if I want to move my wireless card I have to take out graphics card first also because it takes up 2 slots.

    Has the 4870 technology come down to the point it is a single slot card if not is there any other cards that are hopefully with HDMI.

    The HD4870 is available as a single slot card such as this one overclockersclub.com/rev…x2/

    It is HDMI compatible via an adapter.

    That's not quite true, some video encoding software will make use of the graphics card. See the article ]here. That does only apply to software that supports it though.

    I'm fairly sure it won't speed up burning DVDs, the limitation there is the speed of the DVD drive rather than any lack of processing power.

    As for which graphics card is the best, as I said in the previous ]thread you need to find out exactly how much power your power supply provides on the +12v rails. Having two of them is a good sign and your power supply may be able to handle quite a powerful card for it's rating.

    You don't have any PCI-E power connectors so the highest performing cards that can physically be connected would probably be the ATI Radeon 4670 GDDR3 version (e.g. ]this) and the nVidia GT 240 GDDR5 version (e.g. ]this). There's a review of the GT240 GDDR5 ]here that includes numbers from a GDDR3 4670.

    The 4350 is the slowest dedicated graphics card you can get, it's really not worth it if something better will run. It's probably a quarter of a fifth of the performance of the two ~£60 options. I don't know what PCNextday (who built the zoostorm PCs) are like about power supplies but it doesn't use that much more power than an extra hard drive or general add-on card so it would be fine on most PCs.

    As to the 4870 the newer technology lower power equivalent would be one of the 5000 series but despite the lower power consumption ATI has given all the reference designs dual-slot coolers. No doubt single slot versions will be available sooner or later though.

    Yep that is interesting and the cards offer HD acceleration as with most GPUs currently on the market. If the video to be encoded/decoded is using other mainstream CODECs that are not recognised by the card there is no acceleration but I do see the popular H274 codec is supported.
