I work for a pc component manufacture named ASUS. Since I were going to updrage my computers this week I had a big test session in the office last weekend to find out the ultimate config for running 5 and even 10 wows on the same comp.

Best w/o cost limit:

CPU: Intel QX9770 clocked to 4GHz (Quad core 45nm).

Motherboard: P5E3 Premium X48

Memory: 4x2GB Corsair Dominator DDR3 1600MHz 8-8-8-22 (8GB in total)

Graphic card: Nvidia GTX280 TOP 1024MB GDDR3

Storage: Intel 64GB ES SSD (extremly high perf. but not available in stores yet)

OS: Vista Ultimate 64bit

Conlusion on this config: It seems like the driver needed to run GTX280 has a problem with rendering a perfect image of more than 1 source at once. Resulting in artifacts when using this card. The artifacts are not very noticable so I dont count this as a problem. If you cant find a high perf. SSD WD Velociraptor would be the best choise. This rig runs 10 wow smoothtly.



Best config with a good c/p ratio:

CPU: Intel E8400 clocked to 3600MHz (dual core 45nm)

Motherboard: P5Q Deluxe P45 DDR2

Memory: 4x2GB corsair value memory

Graphic card: Nvidia 9800GTX+ (no artifacts what so ever, perfect rendering)

Storage: Two single platter 500GB HDDS in Raid 0 (using drive Xpert on P5Q).

OS: Vista Ultimate 64bit

Conlusion on this config: 9800GTX+ gives you a perfect rendering (even on two screens). This config allowed to run 10 WoWs (9 minmized and 1 visable) in zangarmarsh at 60fps constantly smothly.

What I've learned from my testing:

4GB of system memory will allow you to run up to 6 WoW in Oggrimar without lag, 4 WoWs in shattrath.

6GB of system memory will allow you to run up to 10 WoW in Oggrimar without lag, 6 WoW in Shattrath.

8GB of system memory will allow you to run up to 10 WoW in Oggrimar without lag, 8-9 WoW in Shattrath.

A G92 gpu based graphic card like 9800GTX is the best. (If you have a G80 8800GTX or Ultra that is just as good)

DDR2 for sure since 8GB comes at a much better price than DDR3. Mmory bandwidth is not very important.

SSD storage is the best for sure, especailly in oggrimar or shattrath

A intel E8400 will give you all the cpu power you need.

Do NOT get a AMD graphic card. AMD has a driver limitations so it can only render 1 3d source at one time correctly. So you cant run more than 1 wow with a AMD (ATI) card.

Do NOT use SLI or a 9800GX2 card, it will limit you to one display.

Your graphic card should not have less than 512MB frame buffer.

GTX280 offers the best multiboxing graphic performance with its native 512bit 1024MB frame buffer. (will give you some artifacts though)

In the end if you want to multibox more than 5 use 2 computers it will give you the best performance

I multibox 8 warlocks, 1 paladin and 1 druid and by using two of the last system listed here I get perfect performance using two 24" and two 22" displays.
