GPU/Motherboard Compatiblity

[DavidYpres]

Alright so, I've finally built my rig and the relevant specs are as follows:

Crosshair V Formula Z
Asus Direct CUII R9 290
16GB G.Skill Sniper 1866MHz
FX 8350 w/ Thermaltake Water 3.0 Ultimate
EVGA SuperNova 750 G2 Gold
Blackhawk Ultra Case

Now on to the questions. First I know I'll need a stronger PSU for this, but I'm aiming to save up and purchase a R9 395x2 once those pop out on the market. However, I undertsand that this will be PCI-E 3.0 which is not a feature of the Formula-Z motherboard. Will this negatively impact the performance of this card if I use it in conjunction with this motherboard? If so, would it even be worth it to get a 295x2 and what would I see with regards to improvement over my current card? I understand 3.0 is backwards compatible with 2.0 but I've read that it's just not quite as good as if I were to have a 3.0 slot.

 

As a side note, I overclocked the CPU to 4.8GHz following the ROG guide to do so. After running Prime95 the CPU temperatures were hitting 60-63 degrees. I feel like that's a bit high even with the cooling solution I've got. I followed those instructions perfectly so I just want to make sure there isn't anything else I could have done to reduce the temperatures.

 

Pardon my n00bishness.

Thanks in advance.

Does your mobo have PCIe? Then it'll work.

Yes.  I have PCI-E 2.0 but this card will apparently be PCI-E 3.0 natively.

It'll downgrade itself, it'll still work

Stop thinking too much, you'll get stressed
