My cousin has a PNY GTX610
that is GDDR3 and he got a new motherboard that only supports GDDR5 Graphics card. The motherboard is a MSI 970 Gaming
for his new build. Should he use it with the motherboard or should he not??MSI 970 GAMING http://www.amazon.com/gp/product/B00LUY72F6/ref=crt_ewc_title_dp_2?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
That is a PCIe slot. It may be x16, x8 or x4. They are not GDDR5 or 3 slots. The version of the slot may be PCIe 1.0, 2.0, 3.0 or higher. That is a PCIe 2.0 card. Most likely if he bought a very recent board it is a PCIe 3.0 slot which is backwards compatible.
Long story short? Yes, that card will work.
The manufacturer suggests a 350W PSU.
EDIT. They are PCIe 2.0 slots. Perfectly compatible.
