pentium D 920 is crap compared to the athlon x2s and especially the c2ds. 2.8GHz on a Pentium D is like 1.5GHz on my Core 2 duo... I'm running my c2d at 30GHz FYI with plenty of room to be upped. that system also ahs a ---- GFX card and likely PSU. it would likely suffice but not something I'd use for a 24.7 gamer seeing as how you'de need to upgrade the GFX card off the bat, it has limited upgradeability and it costs a fair amount. 6200LE is absolute crap FYI. ABSOLUTE.
