Hey guys, I'm a mid-range gamer with the following current specs: Athlon 64 X2 4600 2.4GHz XFX nForce 590 SLI mobo 6GB Corsair DDR2-800 PNY 7900GS 256MB x 2 on SLI I'm hoping to spend ~100-150 to upgrade my video to play Dragon Age and MW2 without a new mobo (which unfortunately is only PCIe 1.0). I'm considering a Radeon 4770 512MB or GTS250 1GB - What are people's thoughts? I can spend the extra $20-30 for a 4870, but is the bottleneck at PCIe 1.0 worth it?
