Spec me a CPU and RAM upgrade

[NvidiaDan]

Hey guys, Looking to upgrade my CPU and RAM to increase my chances of getting half decent frame rates in GTA4 and Crysis

My current spec is:

Intel [email protected]
Corsair XMS2 2gb RAM
Asus P5Q Mobo
BeQuiet! dark power pro 450w modular PSU
Nvidia 9800gt 1gb

Hoping you guys could point me in the right direction Got around £200 to spend. Preferably socket 775 CPU that is compatible with my motherboard and around 4-6Gb of RAM

Thanks guys

Ahh thanks i was just looking at the 8400 as well. Would it still be ok to run on my 450w PSU? As for RAM i was looking at this http://www.overclockers.co.uk/showproduct.php?prodid=MY-008-PA&groupid=701&catid=8&subcat= Does it look OK?

Edit: Just noticed you suggested the E8400 but i was looking at the Q8400 would that be ok? or are there better Quads for the money? And yeah, My CPU is overclocked

Bit more than i can afford though if i want to get RAM aswell

 

[NvidiaDan]

OK, just been looking at RAM Narrowed it down to these to so far for performance for money.

What would be the best choice out of those? or are there any others you think are worth a look?

 

[NvidiaDan]

Ohhh, Thanks will look into it and let you know when i have made a decision.

One more question Would the OCZ 4gb gold edition RAM that siumatfung suggested run ok with my existing Corsair RAM? Or would i only be able to run the 2 sticks of OCZ? Thanks

 

[NvidiaDan]

Anyone?

 

[NvidiaDan]

Yeah, Im on Win7 RC 64bit

Thanks, But what i wanted to know was if i bought the OCZ ram could i just put it in the 2 available slots with my existing RAM with no problems, or would they cause errors as they are made by different companies?
