Hello, Im a huge noob at PC building and general knowledge, I have a computer ive had for a few years now and wish to upgrade it, The current Graphics card is an Nvidia GT545 3gb DDR3. The mother board is an Asus P8H67-M, and it has Intel Core i7 2600, if i purchase a 750w PSU first, will a "Gigabyte R9 290X 4GB DDR5" graphics card be compatible, I believe the motherboard has PCIEX16 1.0? will it work? if not can you recomend a card that would give the highest performance with this configuration?
Thanks
Thanks
