no intention of SLI/Crossfire. planning to keep my setup below SGD1000 so thats ard USD800.
i dont intend to play games like crysis, but maybe BF3 and starcraft 2?
can you elaborate on the features between H77 vs B75?
and my cpu wont be a cause of bottleneck will it?
B75 is meant for business systems that use a lot of older hardware - it includes ports that haven't been used in like a decade. H77 is more up to date and includes more SATA, eSATA, and USB 2.0 and 3.0 ports.
The 3450 definitely won't be a bottleneck in that system - it's an excellent CPU.
