I was just wondering if there's some sort of guide on which processor + video card combo would suit best (so that they won't be bottlenecked by one another).
I planned on making a rig with a Q9550 processor, and a GTX 285 (or an HD 4870x2) vid card.
The quick and dirty way to do it is look how much the processor costs, and then spend the same amount of money on the video card. It won't always pair perfectly depending on market prices, but more importantly, you won't be wasting money on GPU power you can't take advantage of.
