I have an acer m3970 with a 3.1 ghz i5-3450 cpu. I am planning on getting a new gpu for this machine, as well as a new psu (gtx 660 non ti) and i think in the near future a new cpu would benefit performance quiet a bit. I was thinking a i5-3750, would this computer allow me to upgrade this cpu like that? how would i tell? i cant seem to find the motherboard of this computer so i can't even try to search and see if the motherboard is compatible. Thanks so much for your help in advance guys!
