Not at all, most applications are not dual-cpu-capable (lieke almost every game), but let's say, when you use lots of applications at the same time (soltär&minesweeper ;D), windows will react a lot of smoother.
So just for gaming it won't be faster (same like the dualcores, at this momnet they won't give you a speedboost ).

Quad? At least $1500 for the Board + four 8xx-Opterons?

If you're only looking for speed in gaming, for the money you must have for the quad-system, you can get va perfect uptodate gaming-system .

Sure, look on this hompage by the user Tom.

also what about sata 2 drives?

wil they increase gaming speeds?

SATAII is just the interface, so same drives, one with SATA1 and one with two would give the same speed (but in fact, SATA2-Drives are newer, so if you compare the old and the new 160er-Hitachi you will have a little bit more speed with the newer one). If youre just looking for speed: 4x 74-Raptors in a RAID0 (but don't forget the backups ;P)

err he has got 2 pci-e slots..
" quad-A64 SLI "

anyway about the Sata II as x-stars said kinda .. it doesn't actually make the drives "Faster" i think it just allows more bandwidth for harddrives... anyway as x-stars said again lol... the 4 * 74 raptors is the best for speed... if you have the data " A B C D" in a normal instance your computer will put A B C and D into one harddrive... in Raid 0 (over 4 drives) it will put "A" into the first "b" into the second "c" into the third and "D" into the fourth harddrive... therefore when accessing the data it will be able to read the data 4 times as fast (in theory). As for the dual cpus... i have dual core and from what i see at the moment it is only bringing problems to be in games.. i have to set the game to only use one cpu otherwise the game acts as though i have a speedhack on lol... IMO you should wait until jan~ when AMD will bring out there dual core 5000+.. it will be more effective i think.

Surly not bad, but that are Opterons, not A64 : - think he got that wrong, but anyway, two CPUs, four Cores - still a system you can dram of ;D.

If you're looking for big watercooling systems, I remember a guy who cools every system in his house with a single watercooling. He uses a big tank and a huge pump downstairs and installed pipes all over the house. Each system has the cooler, a small pump and a small radiator (for off-plugged-use). Because of the extra-pump, he can install the systems parallel on the watercooling without to worry, that the water flows to the first and does not go to the second (as it would without pump, cause the water would use the was with the smallest resistance).

Edit: Oops, just saw, Tom did not cool his "A64-rig" per water, but you can see a "normal" Dual-Opteron there, too.
