Re: If anyone is a computer junkie... please help.
Ouch, you're still using an athlon x2 and a 9500... TBH, both of those need to go before you will see significant improvement in high end games, but the 9500 is most likely the bottleneck right now.
For a $100 budget, I'd recommend a GTS 450. I think it was newegg that has one for $80. The HD 5750 or 5770 would also be excellent choices, but I haven't seen any with big discounts yet.
