Ok, so I got like $900 in tax refund money, and I want to upgrade my computer. Right now I have a Dual 2.4 GHz Xeon system with a Geforce 4 Ti4600. My motherboard doesn't have any PCI-E slots so I want to upgrade to a system with that. So far, it looks like it will cost about the same to switch to a dual-core system rather than just upgrade my board to handle PCI-E, only the dual core boards are a lot better.
So basically, I have 900 bucks, and I want to know the best video card/motherboard/processor, or motherboard/video card combos I can get for that. I prefer nVidia cards for video mostly just to avoid the driver issues that come out with pretty much every game for ATI cards.
note: this is in canadian funds.
