Hi,

Newbie Builder Here. What exactly do you have to look out for to make sure a GPU is compatible with your MOBO & CPU? The GPU I’m interested in getting is the Radeon HD 7850, will it be compatible with my current system (listed below)?

Also, the Radeon HD 7850's that are listed on Newegg come with various company brands, Saphire, Asus, Gigabyte, etc.. Does it matter which one I choose?

I don't see why it wouldn't work. Is your PSU from a good brand? Corsair, Antec stuff like that? It will probably run on a general brand but you could fry something up.

if the mobo has PCI express slot x16 it will work... since you are getting the 7850 wich supports pci 3.0 slots, you could go with a mobo with PCI E 3.0 slots that in the future if you change to a Ivy bridge CPU it should give you a boost in performance, but right now just pci e x16 2.0 will do the job.

About the GPU, best is look for brands that give you good supports, and have a good warranty period, basically the brands difference is that, and each brand sells various models of GPUS< some with reference cooling, and some with non reference coolers that are normally more silent and can be overclocked to higher speeds.

Well the PCI e x16 is actually 1.0 ... but I'm guessing it should still work with the GPU. What about the impact on performance, will it be noticeable using a 1.0 instead of a 2.0 or 3.0 PCI e?

if i'm not mistaken the pci e x16 1.0 is equivalent of pci e x8 2.0 so the performance impact over the 2.0 is minimum, less than 2% of performance loss, and PCI E 3.0 up to now gives 0% performance over 2.0 so for now it is useless, this should be improved with the Ivy bridge CPUS.
