64GB may be a little tight, I have a win 8 media center and now I've installed a few updates etc the drive is over half full. Fine on the media center but for a desktop PC 64GB soon becomes cramped especially as for a decent SSD life you should keep 25% of the drive empty.
If you can, get a 120GB version. I have plenty of SSD's now and I recently got a great deal on a Sandisk Ultra which isn't the fastest drive on paper but isn't noticeably slower than recent OCZ / Crucial unless you benchmark.
