I currently am running C2Q Q6600 2.6Ghz, 4GB RAM, 2x 1 TB HD drives, NVidia 7900GS, 40" NEC 4020 Monitor @ 1920 x 1080. My comp is struggling to play Crysis. I really would like to upgrade the graphics card to get the most out of my monitor. The 9800 GTX has been on HUKD for a few weeks but i am not sure about upgrading to old technology (as in is it futureproof??? i mean GDDR3 Vs GDDR5) and would prefere to spend a little more and get a HD 4850 or HD 4870.
Please could you suggest wheather I should just buy a 9800 GTX or HD 4850 or should i spend £50 more and get a HD 4870.
Also please could you guys tell me wheather is worth purchasing a PhysX card??? will this improve my gameplay???
If i were to purchase to HD 4870 should I wait for the price to drop or buy now???
