I have a pretty big dilemma here. My current system is getting pretty old. Besides my Radeon HD 4670, everything is pretty outdated: Intel Pentium 805 2.66 GHz overclocked to 2.96 GHz 2 GB DDR2 PC4200 RAM @ 533 MHz Intel D945GCCR Motherboard - doesn't support anything past the old Core 2s. 450 Watt Power Supply Sony Light Scribe DVD/R+W ATI Radeon HD 4670 1 GB DDR3 Western Digital 250 GB 7200 RPM Hard Drive So basically, in order to upgrade my processor, I need to swap out the motherboard and since new motherboards don't even take PC4200 RAM, I need new RAM as well. I'm thinking between two different setups Intel Setup Intel Pentium Dual Core E6300 @ 2.80 GHz (overclockable to > 4 GHz) Some Asus or Gigabyte P43 or P45 motherboard 2 GB DDR2 PC6400 800 MHz RAM This setup costs around $200 AMD Setup AMD Athlon II X4 Quad Core @ 2.60 GHz (overclockable to about 3.5 GHz) Some Asus or Gigabyte AM3 motherboard 2 GB DDR3 1333 MHz RAM This setup costs around $230 I've never had an AMD computer in my life, but having the Quad Core seems very intriguing and can possibly set me up well for the next couple of years, although the dual core should be still good for a couple as well at overclocked speeds. Can those who have experience with AMDs possibly give me some advice on overclocking and their reliability? BTW, I'm also considering the Phenom X3s. The deal breaker for me here is that the Quad Core requires a lot more power and I have a cheap ass 450 Watt power supply. I don't even know if that thing can handle the 400+ W load of the quad core + overclocking. Plus, I don't have enough money to buy a really nice power supply at around $100. So those with experience with AMDs, please fill me in.
