looking into multi-boxing

hello
I recently became interested in multi-boxing after i talked to someone on my realm who played 5 shams.
I am in the middle of building a new comp (woot).
Asus P5K Pro LGA 775 Intel P35 ATX Intel Motherboard
Intel Core 2 Duo E4600 2.4GHz 2MB L2 Cache LGA 775 65W Dual-Core Processo
2g ram now 4 soon
going to buy a new video card soon any suggestions?
still haven't decided on going for 3-5 or mage-sham
was wondering if my new system will be able to handle 3-5 clients.
any advice or noobie tips are appreciated thanks :D

I wouldn't get an Asus P5k series motherboard. The BIOS of these motherboards has some nasty issues with detecting the correct memory settings of some memory modules and this can cause your system to become very unstable.

With 2 cores I chugged a bit, but it's doable. A lot has to do with in game settings as well. This is the card I put in my quad core http://www.newegg.com/Product/Produc...82E16814102714
