Is there anyway to use a better Pentium D in here? It's a Gateway GT5014 with a 2.8 Ghz Pent D 820.

What do you mean? Mine has Vista on it so there's nothing left of the OS from Gateway.T-Shirt wrote:Yes Gateway's are stable, but giveup some speed optimazation for that stablity.
Best bet would be to check the gateway site for (expensive) upgrades, ie find other models with the same MB, that have fast processors.
