This is my first build, so I thought I'd double-check with a forum first (hopefully I'm in the right section).
I'm looking for incompatibilities (if any) for PSU connectors/wattage, motherboard SATA/PCI/PCIe bus, or anything else. I did my research though, so I think I should be good, but I don't want to waste hundreds of dollars.
I understand the 480 is hotter and noisier, but I have a big enough case and a modular PSU for ventilation to take care of the heat. For the noise, I'm not sure though. By the way, I can price match the 480 to have it for 200$, which doesn't display on the link I sent. Moreover, the value/performance ratio is very good on the 480.
all of that will work together.
However, I'd suggest the HD 7850 over the GTX 480. far cooler and less power for slightly better performance.
the 750W would therefore be overkill, and a 430-550W would be enough for a single 7850, 600-650W for crossfire.
