Hit the open box, demo, closeout and refurbish sections of Micro Center. Find the best spec'd model from a major brand, for the price you want. And don't look back...agonize about what you don't have...worry about upgrades...Power spec's & bench scores. Just play the games and enjoy what it gives you. You'll likely still be able to get a 1-2 year old model that will be ahead of the new consoles. Target one that has Windows 8.1 and can handle DX 11. Or nothing below DX 10.
