I have a system:
MB: Asus P5Q Pro turbo
VGA: Ati HD 4870 1gb
Ram: 6gb DDR @ 800mhz
CPU: c2d E4700 @ 2.66ghz
I want to upgrade CPU for gaming. My budget is around 150-170. what CPU i should buy for best performance. Thanks
well for you budget u obviously sticking with the 775 socket with that in mind you really only have 2 or 3 choices
1st is a q6600 its an older 65nm quad but can be overclocked nicely 160 to 170
2nd choice would be a q9400 which is about 180 to 190
3rd which would be my choice not evetyone will agree but its what i just built and it runs great is an E 8200 which i just picked one up new for 130
Now with the E8200 i t can be overclocked alot i have mine running at 4ghz on air with just a touch above stock voltage. If you look at benchmarks for games a higher clocked core duo will beat a lower clocked quad core ar "MOST" games there are a few that use more then 2 cores but most only run at 2 so in your budget to get most bang for your buck get an e8200 and overclock it it can go up to 3.4 -3.6 ghz without even breaking a sweat and with a lil know how and alot of tweaking u can get 4ghz duo that will mop the floor with all the quads in ur price range
Cheaper choice would be E7500--it has a high clock but the other stats are weak.
If you are concerned with gaming performance this is the way to go because of the rediculous overclocking power and massive cache-- however if you are concerned with longevity a quad core may age better.
