Hello , I am buying different parts in order to build a decent gaming pc at a relatively cheap price. I would like to know if these four are compatible : - Graphics card : POV TGT GeForce GTX 650 Ti Performance Boost or MSI GTX 650 ti OC Power Edition . What differences are there between POV and MSI? - Motherboard : MSI Z77MA-G45 or Z77A-G45 . I went on the MSI site and I didnt find in the compatibility sheet with VGA cards, the GTX 650 TI , is it normal ??? - Processor : Intel Core i3 3220 Ivybridge - Memory : Kingston 4Go DDR3 1600MHz CL9 HyperX PnP Thank you.
