Hi guys, I just needed some advice as to whether this plan will come to fruition. I have an ASUS EN8800GTS 320MB DDR3 that burnt out (started seeing horizontal spots all over the screen and win7 64-bit won't boot because of it!). Hence, I have decided I will be getting a higher end video card to replace my 2 year old 8800GTS that I had paid $240 CAD for. Also, I had modded the card with a Duorb VGA cooler about a month ago. The new cards I have been looking at seem very power hungry and that is why the GTX260 core 216 (OC) seems interesting. I humbly require your expert opinions to help me decide if this thing will work with my rig or not. And what alternatives can i go for. Please note that I am not restricted to NVIDIA; I am flexible for ATI's as well... My rig specs are as follows: Motherboard with only one PCIe x16 slot AMD Athlon 64x2 4400+ @2.3GHz (AM2 socket modded w/ 92mm TR2 fan from Tt) 6 GB DDR2 RAM @ 533MHz 500W Antec PSU (SLI ready) NZXT Zero2 Case with 5 x 120mm case fans (3 LED) 2 SATA HDD (one of them is a 500GB Hitachi 7200rpm; other 1 is Seagate 160GB) Windows 7 RC 64-Bit Your thoughts are MOST welcome!
