Upgrade / Bang for Buck

[triggerthat]

Hi all,

I have a Q6600 at 2.9Ghz with a 4890. It plays everything quite well. I've been having problems with Metro 2033 where it gets very chopping. It didn't do this when I first installed the game so will need to troubleshoot that.

Anyhow, I was thinking of upgrading my graphics card and me always enjoying the bang for buck upgrade, I went from a 8800 GTX to a 4890. I want to ask what is a good upgrade to go for (second hand to save sweeten the deal)? I was considering the 5870. They go for around the £130 mark on the bay.

Is there any other card I should consider? Is there an overall benchmark which compares all cards?

If your 4890 plays things quite well for now, I'd suggest holding off a GPU upgrade for a bit maybe? Buy a CPU cooler and OC your CPU. Save a bit more money and buy a new GPU later?

Good idea. I can clock my Q6600 to 3Ghz. It's a g0 version and it has an artic 7 cooler. Anything higher then it crashes. I am assuming I need more volts to get it stable? What volts would it need for a 3.2Ghz?
