Windows 7 isn't released so the issues of drivers and the lack of support may dog you for the next month. When Windows 7 ships there is usually a delay till the drivers become "official" and the support for your machine can answer your questions.
Looks like great choices but you are in "the unsupported land."
I'm afraid I'm not exactly a pro with computers so you will have to excuse my ignorance. I have a fair idea of what I'm doing so I hope this all makes sense.
I've had issues with my Nvidia GTX 260 and had to send it back. As the company I bought it with no longer stock it, I decided (perhaps stupidly) to upgrade to a BFG GTX 295. I'm working through a lot of upgrades to my set up over the next month or so and will soon be purchasing 8GB RAM, Windows 7 and a 24 inch monitor running at 1920 x 1200 resolution.
My bro will be helping me to ensure everything is running to its full capacity, but my main worry is that I've made a mistake going for the GTX 295 now, when I'm reading that it isn't directx 11 compatible. This is primarily a games machine and I was hoping it could handle anything thrown at it for a while. How much of an issue is this going to be for me with the 295 and will I end up having to upgrade to a 300 series when they are released?
Thanks in advance for any advice you can offer.
