Computer Specs - Need Advice

Hey everyone,

I'm helping my cousin build a gaming computer and I've come up with 2 different specs. (The setup I'm looking at is composed of CPU, Mobo, GPU, HDD, Mem Ram - The rest I'll look into afterwards) His budget is limited to 1000 canadian dollars, thus why I'm referencing tigerdirect.ca.

I'm trying to figure out wheter everything will run just fine without any compatibility issues and if there's any gaps that could be improved within the budget limit. I appreciate all of your help.

Setup 1 - ATI GPU, etc.

CPU - Intel Core 2 Quad Q8200 Processor BX80580Q8200 ($200) [link]
