thanks for all the help, guys. It's been a year already since I posted this thread.
Got a lot of upgrades on my rig now. Got an 8500gt, 9400gt, gt 430, and planning to buy a new one this year. Same old cpu but overclocked at 3.07hgz. Got 4gb of ram now. And some performance-enhancing software to boost my rig. Also planning to buy anpther HDD, because my currrent hdd is almost out of storage space, 2 4GB DDR2 memories, and lastly, a better psu.
