I currently have a Sandy Bridge Intel i7-2600S 2.8GHz. I currently use an old graphics card, AMD Radeon HD 6570. I would like to upgrade to a GTX 670, more specifically this one http://www.newegg.ca/Product/Product.aspx?Item=N82E1681... I would like to know if my CPU will be capable of supporting this graphics card. I don't play games like Crysis, I just play MMORPG and and MOBA games such as DOTA 2. It is ok if I am not using the GPU at 100% but I would at least be able to use the GPU to like 75% of what it is capable of doing. I will be upgrading my CPU in a couple month anyways but I didn't know if it would be useless or not because my frames per second drop when I increase the graphics. I can play on medium graphics at 60 FPS but if I turn everything maxed I drop to about 20. Will this GPU increase my FPS to 60 on max or will it be bottle necked due to my CPU.
PS: I understand that it may be bottle necked but I am aiming for a drastic change in GPU performance. Help is greatly appreciated!
