both retail at around 11-12k.and offer similar performance,which should i buy?
7790 is slightly faster than 650-ti and is the card to buy between the two.
But nvidia has launched another
650-ti boost that is priced similarly with 7790.
Its has more no. of Rops than regular 650-ti ( 24 in the boost as opposed to 16 in normal) and comes with a 192 bit bus.
Comes in both 1gb and 2gb flavors.
In performance, its 30% faster than 7790 and 5% faster than 7850. Wait a bit long and it will launch here at 11-12k.
Check tomshardware recommended list:
Best PCIe Card : $110 To $180 : April 2013
both 7790 and 7850 aren't recommended at their pricepoints anymore.
is it worth forgoing Physx?(i really want to play Bor2,B:AC,P2 with Physx turned on)
one more thing,is TresssFX AMD exclusive?
TressFx isn't exclusive to amd. Its a dx11 based method that uses direct-compute.
