Update and request for more insight. PC Club is really taking my order and running with it. I think they want to prove out this system for themselves so they have the moxie to put monsters together. Anyway... They are getting spectacular ratings on the overnight benchmark tests on the RAM, the Motherboard and the Raptor Array. They have more things they want to do, so I am patient and letting them have their way with the sys! My salesman Jeffery just called. He wanted to give me the heads-up that apparently on the PC 4Gigs of memory is nice, but does not yield 4Gigs usable...they are getting readings of 3.6 GIG yeild, with the issue being that XPPro is loading Southbridge into memory and that is locking up the .4 gig missing. He said 'none of the motherboard manufactures seem to think this is anything negative' and that in addition to the actual numbers they are seeing on the gigabyte board (bios 3.7G, windows3.8) that the other boards' user manuals say that effect will also show up on theirs. Abit said their board would be very close to 4Gig, but at 333, not 400. I nixed that notion. Any comments from you guys? BTW, here are the boards that were considered, we are going with the gigabyte. ASUS ASV Deluxe ABIT KAT800-939 AV8 GIGABYTE KSTriton series, NS Ultra-939 Jeffery said "This thing is really flying" about the system so far. I am drooling. ::::: Opera :::::
