$400 to upgrade PC what do you recommend?

[sublimedust17]

Hello,
My current PC specs are:
Intel QQ6600 2.4ghz (Quad-core)
3gb DDR2 ram 800mhz
ATI HD5750
500W Power Supply
250gb HDD
Asus P5K motherboard socket LGA775
I currently have up to $400 to spend on upgrades. I play a lot of games which it handles fine, I just want to be able to crank up the settings what would your recommend I upgrade?

Frankly, just get something to overclock the CPU. In my opinion, this thing is still to recent to do a full rebuild which is the only way to get any better than this. So I'd say wait another year or two and do a new build then. Otherwise, it'll just be slightly faster.

Of course, you could also put some of that money to upgrade things that don't get it often, like monitors, speakers (possibly surround sound setup), or even gaming mouse and mechanical keyboard:

You can get a cooler like the Hyper 212 Plus and some thermal paste

And OC that CPU to 3GHz.

Then get a new video card. A HD 6950 would be nice.

Q6600 might be a tad lowly clocked for today's games so all u have to do is grab an after market cooler and OC it so agree with the advice above hehe

Also state exact model of PSU, resolution u wanna take games to, etc
