Ok so tomorrow I am going to buy the final parts for my gaming computer. I was planning on going to buy the NVIDIA GeForce GTX 550 Ti since the GTX 560 and GTX 560 Ti are out of my budget. However, I stumbled upon the NVIDIA GeForce GTX 560 SE. I have done a little bit of research and people have been saying that it's just a little bit underneath the GTX 560 but above the GTX 550 Ti. It is also within my price range. I'm wondering if buying the GTX 560 SE really would be better than buying the GTX 550 Ti (performance wise of course). If anyone has any information on this or can give me a comparison of the GTX 550 Ti to the GTX 560 SE, it would be greatly appreciated. Please post as soon as possible. (A comparison of their performance on GW2 would be greatly appreciated as well!)
