The new AMD Radeon HD 7800 series of graphics cards is based on the third family of GPU’s from AMD built in its new 28nm process and featuring the highly acclaimed GCN graphics processing architecture. The MSI 7850 TwinFrozrIII/OC edition, factory-overclocked to 900 MHz engine and effective 4800 MHz memory, offers superior performance than standard models. It is equipped with MSI's TwinFrozrIII Propeller blade to generate 20% more airflow than traditional design and run 10C cooler & 13.7dB quieter than a reference design!!!

Usually it's the CPU that bottlenecks the GPU. You'd only have to worry if you had an older generation CPU.

In this case though, the GPU would cause a bottleneck due to the 1GB VRAM. You'd want the 2GB VRAM model for gaming at 1080p, which I'm guessing you do because of the i5 3570k.

1GB model is surprisingly capable, to quote this review from TechPowerUp

"The Club3D HD 7850 RoyalQueen comes with only 1 GB memory, whereas most other HD 7850 cards on the market have 2 GB. When I first got the card, I was extremely sceptical whether such capacity could provide enough performance for the latest and greatest titles. Now, after finishing the review, I am impressed. At resolutions up to, and including, 1920x1200, the card is just as fast as the HD 7850 with 2 GB, if not a little bit faster. Only at resolutions of 5760x1080 (Eyefinity), and at 2560x1600 in some games, did we see a performance penalty from the smaller frame buffer. Personally, I don't consider this an issue, because a single HD 7850 is just too slow for these resolutions anyway."

Obviously I'd still go 2GB if you can afford it but the 1GB VRAM on the card isn't that big a limiting factor, at least not with the current range of titles (although modding games like Skyrim will see a spike in VRAM usage), although in saying that the 1GB VRAM doesn't seem to hurt it too much in a VRAM hungry game like BF3

Skyrim at 1080p 2gb is almost 70% faster than the 1GB version

I take it this would be a fairly substantial upgrade over a standard 6850?

Not according to that review (although this is 1920x1200)

If it were me I'd stick with the 6850 until the 8000 series comes out as what I'd consider to be a significant upgrade would be a 7950.

2gb 7870 would probably also be quite a jump. There is quite a lot of weight in the 7870 over the 7850.

That's because they've added in the hi-res texture pack, an addition that I said a few posts above would increase the amount of VRAM needed.
