I actually just upgraded mobo, cpu and ram about 4 months ago, last month threw on the Coolermaster N220 Hyper or something like that, its like the V6 GT just not as flashy
Still giving burn in time and nerves to settle before I OC anything, first full build so Im nervous about tinkering too much, alot to be wasted if I break anything and it run soooo smooth right now.
The PSU is actually about 2 yrs old as is the Case, dvd burner and one of the HDs but its supporting the whole system flawlessly. If I do get another GPU for SLI like I want Id need to upgrade, same if I dabbled in Water Cooling but that REALLY makes me nervous... 1 leak and bye bye $1200 system
I would look at a 600-650 if your using a Quad Core or higher wattage CPU or running SLI but unless your system is just retarded you don't need anything too crazy
