Hi guys, i'm new in this forum, cuz i think to be wise enough to solve my hi-tech problems without asking help to others... But competition between ati hd 4890 and nvidia gtx275 created me many doubts. From many forums and tests i understood that gtx275 is a little better than hd 4890, but we must also count the support of cuda and physx tecnology in future and that can make gtx family more competitive than hd... Now i want to buy a new graphic card, and i'm undecided between hd 4980 (180€) and gtx 275(205€), so my question is that the difference of performance between this 2 awesome cards really cost 25€. I know that performance/cost of ATI is more greater than NVIDIA, but my doubt is that nvidia can improve their products with software solution as cuda and physx, and ati does nothing about this.
