will you be overclocking? if not, overkill yung h220, h100 should be more than enough. or kung even standard air cooling fans will be good enough, may separate video card ka naman so hindi naman ganun kainit ang CPU nyan
sa board naman, you dont need the sabertooth, although the other choices you mention hindi ko rin masabi kung ok since kulang yung details sa board na binigay mo. personally, I dont prefer the sabertooth, ok na sakin yung mga normal mobo na high end (my guess is high end naman yung other mobo options mo, they should be enough)
sa case ok ang bitfenix, im using ghost (mas malaki konte sa shinobi and mas marami options sa front and mas mahal din konte)
sa ram, ilang GB yan? 8GB? medyo mahal kasi corsair, you can settle for brands like g.skill ripjaws na ok din naman
sa video card naman, hindi ko rin masabi kung ok or not sa price since kulang sa details. the main difference between single 3GB and 2GB cards is if you go multi monitor (like 3) you can make do with one 3GB card instead of going SLI/Crossfire. if you are not going multi monitor, then 3GB is overkill, 2GB will be more than enough
check my thread, I recently got a new CPU as well, I went AMD but instead of FX, I went with an APU. ang FX kasi AM3 parin ang socket and the 990 mobos medyo rare. kung baga AM3 is kinda old already for me so I chose to go with the newer socket
