Well i just ordered a MSI KT3 Ultra ARU and now im noticing that i could've gotten a KT400 for about $10 more.
My question is...Should i cancel my order real quick and go with the KT400 instead? I've checked the specs on both, and they're basically the same. Infact i think the KT3 that i ordered has more features. Is the only difference, the ability to use 400 DDR instead of DDR333?

Im not a huge fan of PC gaming, so i didn't think that i would need all this memory. Infact i probably will never even use half of the 3gigs the motherboard im getting offers. Oh yea and 1 more PCI slot, so in total there's 6 instead of 5.

So what do you guys think? Cancel the order or keep what i got coming?
