I just copy pasted this from another post, in it im talking about possibly getting the gtx 680. I think my computer could handle it, but one thing im still dont understand is my motherboard has a PCIe2.0 where as the 680 is a PCIe3.0. So what would the difference be? would it be stupid of me to get it, like would I only be able to utilize about 50% of the card since my motherboard isn't 3.0? or if you could give me advice on a much cheaper card that would significantly improve my performance to I could do that. thanks ^.^ right now when running the bench my score was aout 6k-6.5k.

"I wasn't thinking about upgrading my computer, cause I dont have a whole lot of money and im not very tech savy with actually building a computer. But after researching some I think I may only have to get a new graphics card, and not have to get anything else. Would anyone be able to help me out in seeing if my computer could actually handle this type of graphics card or referring me to another cheaper graphics card that would significantly increase performance and allow me to play on max settings no problem?

my specs that i think are most needed are:

Motherboard: http://www.gigabyte.us/products/prod...id=3786&m=n#ov

Only reasion I am including my motherboard is because i dont fully understand if mine will work cause i see alot of ppl saying its a PCIe 3.0 but it will work on a PCIe2.0 which I think is what mine has.

CPU: I have a AMD Phenom II Xi6 1090t
GPU: I have a NVidia GTX 460
RAM: I have 8 GB's
PSU: 800 watts - I included my power supply cause idk if i would have enough power i have been doing a little research on the 680 and i see lots of conflicting results saying that 800 watts would be enough, and some saying i would need over 1000.

Again after reading everyones scores and comparing my system with everyone elses, I have come to the conclusion I will be able to play FFXIV: ARR on max settings smoothly if i just upgrade my graphics card, but not 100% sure. If someone could tell me if im right or wrong it would be much appreciated thank you very much."
