Re: Which GFX card upgrade?
Yep, 5870 is pretty damn good. That's what I would get.
Re: Which GFX card upgrade?
I'm guessing you're running at 1920*1080? I've got a 5770 and it seems to play most of the games I throw at it bar Crysis on max settings and a GTX280 is around 20%-25% better so I really don't think you need an upgrade yet that much.
Re: Which GFX card upgrade?
I have a GTX 275 which is a touch slower than the 280, and I wouldn't bother upgrading to anything slower than a 5870 or a GTX 295. Anything else isn't a big enough jump in performance to justify the price.
Having said that, what game is it that you're struggling to play at settings you are happy with on your current card?
Re: Which GFX card upgrade?
Keep it, dont bother. Theres nothing that would justify its upgrade cost.
