So I'd be looking at a possible PSU and GPU upgrade. PSU is about $50-60 for a quality one (some are cheaper w/MIR's) and about $150-170 for the x1950pro. That is about $200-225 for upgrade. You can get a budget x2 (much better than your current CPU), GPU, PSU, mobo, & DDR2 for about ($65 cpu, $130 GPU, $50 PSU, $60 DDR2) $300 or so. Now that would be a smarter choice, but that is about $100 more than the original option. So you can decide. BTW the DDR2 price was for 2 gig's of RAM, so you could save about $20-25 off of the price if you just got 1 gig, but that is starting to push things. 1 gig would be okay for now if you were running windows XP.
