I'm wondering what graphics cards will work with the Intel DP45SG desktop board. I'm pretty sure any graphics card will work in it but i want to double check. Also any suggestions for a video card under 100 dollars that will run most games on medium settings (minecraft, starcraft II, Total war shogun 2, Civilization 5 games i have right now) this is the link to the board- http://ark.intel.com/products/34683/Intel-Desktop-Board...
That all depends on your CPU, but under $100 bottlenecking shouldn't be a problem.
At that price you wont get a decent graphics card and you've probably have to upgrade sooner than later as no card of that price is future proof to any extent.
Anyway seeing as you asked, a Radeon HD 6670 would be best at that price point!
Hope this helped.
