First post, sorry if this is in the wrong spot. I am looking at two PCs, both with very similar specs. However, one is from Dell with: Pentium® D Processor 820 with Dual Core Technology (2.80GHz, 800FSB) 256MB nVidia GeForce 7900 GS The other is from HP with: Intel(R) Core(TM) 2 Duo processor E6300 (1.86GHz) 256MB NVIDIA GeForce 7500LE, TV-Out, DVI, VGA All other specs are very similar(1 GB RAM, 19" flat screen, apx $1200). Which PC is better for gaming? Which processor is better?
