My mother only supports LGA 775 if possible only core 2 duo's. I play with 1440x900 so i was wondering if an intel core 2 duo E8400 would do the trick.
An Intel Core 2 Quad E8400
would be ample, they are a great processor.
They have six times the L2 cache, twice as many cores, +66% more FSB, and +50% higher clock speed. (vs a Pentium E2180).
In fact you could go for a lower processor, around 2.8GHz (2.66GHz to 2.93GHz)
Remember to double check that your motherboard supports them first (65nm vs 45nm, new stepping & all that).
Also check that your mainboard supports 1333 FSB and that your RAM : FSB ratio isn't going to get messed up or cause system instability and corrupt data over time, etc
People here seem to have forgotten that you specifically mentioned a XFX manufactured Radeon 5750 video card
, not a Radeon 4890 or Radeon 5770
