So I've been upgrading my sister's old P4 system that I recently got back from a person I lent it to. I swapped out 512MB of generic RAM for 1GB of Geil Ultra Platinum DDR 500 which cost me $18, and bought a 3.2GHz P4 Northwood (w/ HT) for $20, and bought an AGP GeForce 6800 128MB for $35. I JUST paid $25 for a Thermaltake Big Typhoon. I'm also looking to drop about $20 in case fans to keep the machine cool. Now, in total these parts will cost me about $120. Minus about $25 for the old hardware that I'm selling, I'd say it would have cost me a flat $100 to upgrade. Here's the funny part, two days ago shev cut me a siiick deal on an unlockable Sempron + 2GB DDR2 + a Biostar 785G board for $87. The performance of the AM3 combo will smack the old 478 system around, no question about it but it would be a huge hassle to swap the parts out. What would you do in my situation, when the P4 system is perfectly good and will run good for years to come, yet the AM3 combo is faster but it'd be a hassle to do an overhaul? What do you guys think I can get for the 478 system on eBay or Craigslist? Maybe I can sell that since it's technically a pretty decent system for a casual web surfer. Keep in mind I'm not going to be a sleezebag and advertise it as a UBER FAST GAMING SYSTEM (back in 1999) THAT WILL RUN ANYTHING YOU THROW AT IT!!!1!@!!@!!1!!
