Ok thx i do have a r2 with 330 power brickwell i think it will depend on what X51 you have if its the R1 or the R2 and what power brick you have.
R1= you might need to purchase R2 power board or slightly under volt CPU and GPU also the 330w power brick is a must.
R2= it will work without any problem if you have the 330w power brick.
just try to get the blower style of the GTX 970 its will be a bit hotter than dual fan cards but its the best choice for our X51 to take hear out of the case from the rear exhaust.
I have not yet made a purchase because i want to if it will actually workCould you tell me which GPU did you order from these or if not can you share a link to which one you bought.
Ok thx for the helpful tipI've seen that before they flashed the evga sc to a stock bios.
Well its your choice after all but I just recommend the blower style cards over the dual fan cooler just for this particular PC otherwise the dual fan will run cooler in a bigger case.
