Getting a new computer but it will need upgrades. I picked out some nice parts but I have one question. At first I'm going to have an AM2 AMD 2.2GHz processor. Please tell me how much this will bottleneck my system. I'm going to be playing pretty much all games so I don't want a bottleneck. If the processor is a big problem then how much can it be overclocked? Hopefully a good 2.6GHz would be fine until I can afford to upgrade it.
