Upgrade from Radeon HD4870 1g

How do you have a lot of ram on a 32 bits OS?

Anyway, for a lot of FPS on gaming you´d crossfire your 4870, if your PSU allows it. In doing so the FPS could pair with GTX 295, GTX 480, GTX 570, HD 6970, and HD 7850, but without the benefits of DirectX 11.

On the other hand if you want to get a brand new card for around $200 then go for:

EVGA SuperClocked 02G-P3-1469-KR GeForce GTX 560 (Fermi) 2GB 256-bit GDDR5 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

or

MSI R6870 Hawk Radeon HD 6870 1GB 256-bit http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I had a pair of 5770's and they were great. If you check out this chart

You should be able to answer your own question. There is another website which you can do one by one comparisons with a bunch of stuff really nice but cant find it. In any case there are def better options out there than a 4870. But if you want to see some real improvments. You should upgrade both VC and CPU. Back to your question I would go with a 6870 in CF

With a video card upgrade budget of $200, you'd be wasting your time upgrading the cpu. Most games today simply aren't nearly as limited by the cpu as they are by the graphics card and your cpu would be fine with a $200 card I think.

I support the idea of a 6870.

thanks for the input. im starting to see pixel 'issues' while playing crysis2 and bioshock2 so i suspect my card is going bad.

lots of ram: 4 gigs of ram without knowing the actual brand as i didnt feel like opening the case just for that.

thanks gents, ill take a closer look at the 6870.
