Getting a ne pc

I'm getting ready to build a similar rig for P3D. As other people mentioned, stick with Windows 7. Crossfire with 2 780's is pointless with FSX, and altogether depending on what monitor setup you are using. All of these newer cards are powerful. People brag about and hype certain vcards yet they have not benchmarked them enough to compare them with others in the same range. Depending on addons or if you are going dual-boot, don't waste your money on extra ssd's. Modest OC on a 4770 will get you 4.1-4.2. You can always upgrade hardware more later if you need it. If you're a multi-gamer, save your money and get a 3-D setup for the games that play well under 3-D. That is by far the best, most captivating upgrade I've ever done.
