I'm thinking of purchasing a new desktop computer with an AMD Phenom quad-core processor running 64-bit Vista. The sole purpose will be to run multiple instances of MT4 each running an EA against a separate account.

Does anyone have any comments about any compatibility issues I may run into? I thought the quad-core processor with 64-bit Vista would be the way to go, given the multiple MT4 instances. But would a duo-core Athlon with 32-bit Vista serve the purpose well enough (and obviously without any compatibility concerns)?

Thanks.
