Hello everyone. I currently have 2 gtx 465 cards on SLI. EVGA GTX 465 1GB. They have served me well but thinking that was like 3 years ago. Should I upgrade to say the GTX 760. Will one card be enough to see good improvement or do I need 2 of them and set them up in SLI. My system is: Processor: AMD FX-8150 overclocked @ 4.2Ghz Memory: Corsair vengeance 2x8GB DDR3 1600Mhz Motherboard: sabertooth 990FX Cooling: Cooler Master RR-V6GT-22PK-R1 Disk Drive: Plextor DVDR PX-L890SA ATA Hard Drive: Western Digital WDC WD1001FALS-00j7B1 / WDC WD1002FAEX-00Z3A / WDC WD1002FAEX-00Z3A0 Power Supply: Antec High Current Gamer Series HCG-900 900W ATX12V v2.3 / EPS12V v2.91 SLI Certified CrossFire Certified 80 PLUS BRONZE Monitor: LG 42" 1080P 60Hz LCD HDTV 42LK450 OS: Windows 7 Professional N x64 SP1 Build 7601. Any suggestions greatly appreciated. Additional question, should I set the Phys X to be controlled by CPU/one of the SLI cards/ or automatic?
