What video card would be better for my current pc set-up?

ATI's 4770 512ddr5 128 bit dvi

5770 512ddr5 hdmi

4770 512ddr5 128 bit dvi

4850 512ddr3 256b hdmi



what card would greatly increase/improve my gaming experience in terms of "FPS"/Frame rates per second at a fairly High Quality Settings?



my previous card is 3650 1gb ddr2 128bit dvi.

i have - Intel Q6600 Core 2 Quad

and 2gigs of ram (i'm planning to upgrade it to 4gigs)



please i need feedbacks. =(|||Go with the 5770. I believe it's directX11 ready. Windows 7 uses dx11 and it's supposed to make graphics perform better. I bought the 5870 myself. If I had more money, I would have bought the 5970. I didn't have $600 though and my GF would have flipped out even more than when i told her I spent $400 on the 5870. The 5870 is fricken awsome though. It runs farcry 2 and Battlefield bad company 2 at max quality and resolution and aa very easily.|||depends, for ur computer i would say a 4870 or 4890,

but if u can only choose from the cards u listed, the 5770.



the 4870 and 4890 is around 3-10% faster then the 5770 but 5770 generates less heat, and uses less power, also supports DX11 (thu its a budget card so dont think DX11 will run very well on it)

im happy with my 4890 :D maxxing crysis with it right now :D
