Gtx 770 or r9 280x

The 280X was supposed to be around $300, which was a better value than the $350ish 770, but they're either sold out or selling for closer to $400, making the 770 a better value. If you aren't pushing multiple monitors then the GTX 760 for around $250 is probably your best bet. You can even spring for the 4GB version for around $280 to help with the highest levels of AA.
 
I would 4 sure go with NVIDIA (there is an answer) ATI doesn't have a software drivers that can do what NVIDIA can ... why picture has more delay after U move a controller (mouse, keys, wheel etc.)

There is an option in NVIDIA control panel :
MANAGE 3D settings / PROGRAM tab (don't change Global tab ...)

look 4 game (or add executable if it isn't found automatic)

option is
MAX. PRE-RENDERED FRAMES (application defualt ----->>>> change to 1) 😀
(still u need DDR3 higher than 1333mhz for new games)

this will render every frame as you move your controler (ATI draws 3 frames in front thats delay (NVIDIA also by default)
but ATI can't change this for 2,5 years now (even before we needed to install only driver for ATI (without catalyst & then ATT (ati tray tools) which are no longer supported by unofficial programer Ray Adams, who retired after many years .

SO I love RACING simulations & I always rather down the max detail & use fast response otherwise there is not real enough feeling of GAME.

Sure the same is with other games (U need to feel them more in present time) :wahoo:

HAPPY NEW YEAR 2014 & stay well (healthy don't sit too long) XD

P.S: got my DDR3 MUSKIN REDLINE 1600 7-7-7-18 1.65v to 1400mhz 6-6-6-15 2T 1.56v (LOL almost no diference but less lag and voltage to i platform (prolonges CPU) still such DDR is very rare (next i'm buyin 2x4gb CRUCIAL Tactical LP 1.50v 1600mhz 8-8-8-24) 8gb work faster & windows get to cache more into DDR not swap file 😉
still for new heavy games still need 1600mhz like Crysis 3 & BF 4 but WOT works swell & HARD RESET is abnormaly fast
