I like the gigabyte gaming 5 ATX the most but if you like MSI better than go for that one. I also don't know what case you use, so if you need mini ITX the gigabyte gaming 5 mini itx is the best.
Can you tell me your situation? Because you said at first you wanted one for under 90, but now you want one for under $150?
