What OS are you going to use? 2GB is a bit low for Vista/Win7. Should be 4GB and Win7 64 preferably.
Check the "charts" section for graphics cards and see if the 5750 suits your needs. Usually its not very much money to move up to a 5770, which is a substantially faster graphics card.
700 series chipsets are old, you should be able to find an 800 series (870, 880 or 890) motherboard with USB3 for around the same price.
