I'm currently looking into upgrading either my cpu or gpu but I'm not sure which to do first. I mostly game on my pc. Currently I have a amd athlon 3200+ and an ATI x700 pro (PCI-E.) I'm looking into getting either a x1800xt or x2 4200 (when the price cuts happen) for my upgrade. Which will best increase my performance on high end games (ie ghost recon advanced warfighter) and will having either the GPU or CPU so much better then the other be a problem? Sorry for the wording its hard to convey my question, so if you need more clarity just say so. Thanks!
