Graphic card Performace
 

Hey Guys I want to buy a new graphic card i got messed between Ati & Nvidia Series, I have also googled them but can't fixed the appropriate once, so which will be better on performance level as well as price
My System Configuration Are As Follows:
Amd Phenom 6x 1055t Processor 2.80ghz
4gb ddr3 ram run on 1333mhz
600watt pure power supply
am3+ GIGABYTE motherboard
500 gb hdd
nvidia gt 240 series graphic card
17" led hd monitor

I have already use nvidia & wanted to buy Ati card with a additional power supply port on it, nvidia is fine for me but on mid level setting on games it seems to be hanged and get slow down, so which one i should buy under 10k
Note: Additional Power Supply Port Should Must:D

Some say ATi is better with AMD; I mean AMD is better with AMD. :) I got mentally stuck in the era where ATi drivers sucked and nVidia drivers were functioning properly but, I admit, it seems to be just the opposite these days. I would rather recommend ATi/AMD.

I'm also looking for a video and can't make up my mind between the 7970 readon or gtx 680 but i went to a computer store and they told me the AMD chip doesn't matter with video you buy ? i only ask this becuase im going to buy a GTX 680 video with a 4 ghz eight-core AM3+ cpu... does it really matter ?

if price isn't an issue buy the geforce gtx 690 $1000 :) For me x-mas is coming early and I'm going to buy gtx 680 ive seen lots of reviws and benchmarks and I'm loving it, it runs for about $500 the radeon 7970 runs about $350 and is a high end card but is a little slower then the gtx 680... these price quotes come from newegg.com
