Thinking of swapping out my GA-EP45-UD3R with a GA-EP45C-UD3R...do you think I will need to re-install Win XP or since it's the same chipset and hardware (other than DDR3 RamI'll be switching to also)? My DDR3 system at work feels just so much smoother that I'm getting dissappointed with my home pc. I'm thinking it also maybemy Seagate HD that might also be the issue, I'm not sure. Any comments or suggestions welcome.
