Ok so here's the thing, I was thinking about my specs and stuff and they're sweet and all, but I was wondering what things I could add to make the it even better...

1st of all, this is what I've got

CPU: Intel E7500

Ram: Random 3Gb

Mobo: Asus P5Q Pro Turbo

GPU: Asus GTX 275 896MB

PSU: Crappy thing I NEED to change hahahaha

ok so those are my specs, and as it says the 1st thing i'll be doing will be getting a new PSU this Christmas to sure up my PC. Anyways, I was supposed to get a Q8400 but the guy my folks got the part from told them that the E7500 was better and screwed them over. So that got me thinking, since my Mobo can take a C2Q would it be worth it upgrading up to a Q9400. I'm not sure what the differences would be, but I'll research it when I have time after exams, so for now I thought I'd just ask you guys......or heck maybe even going up to an i5, but the only problem with that is having to get new ram and motherboard to ssupport it, so what do you guys think.

Also my ram, I've got some budget no-name ram, and I was thinking of selling that and grabbing so proper gaming ram, would that affect my performance enough to warrant the price?

Thanks Guys :)
