I am buying a new graphics card. My current graphics card is an AMD RADEON HD 7520 which is decent but can't run more than 1 and a half hours on FSX. I am planning to buy a better GPU so when the PMDG 777-300 comes out I can FINALLY do long hauls. I want a graphics card that can last for more than 17 hours on ultra settings fsx but I dont want to spend to much on it. Will the GTX 660TI do the job or should I get a GTX 760? 

 

Still wondering... And what kind of GTX 660 or 760 should I get? TI? Superclocked? 2GB? 

 

Thanks, Andrej

If you can afford the GTX 770 go for that

I would also say go for a high GB as you can also afford, 3 or 4 GB will be plenty, infact in theory 2gb should be fine.

As Adam said, if you can afford it, go for the 770.  If not however, out of your 2 choices, get the 760 which is more comparable to a 670.

I have got the msi GTX 760 4GB card which is better for fsx for the price. Go for a card with as much Vram if you can afford it.
