I want to buy a new processor for my Gateway 310 Series, I am between the Pentium 4 Northwood socket 478 or the Celeron D 2.8 Prescott. I do some gaming, specially GTA Vice City, Soldier of Fortune II: Double Helix and some other old games. I currently have a :knock: Celeron 2.6 GHZ Northwood 128K Cache, Barracuda 40GB 5400 RPM ATA 100 hard drive, ATI Radeon 7200 32MB :knock: PCI 256MB DDR 333 MHZ PC3200. I want to have the most frames per second out of this machine. Any upgrade suggestions will be very nice. Thanks.
