So, in helping my fiancee find ideas for building a new gaming rig, I found myself wishing that I could upgrade some parts of my PC. Currently, this is what I have running as far as CPU/Mobo/Power/RAM: ASRock X79 Extreme6/GB LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CORSAIR Professional Series Gold AX850 (CMPSU-850AX) 850W ATX12V v2.31 / EPS12V v2.92 80 PLUS G.SKILL Ripjaws Z Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Intel Core i7-3930K 3.2GHz (3.8GHz Turbo) LGA 2011 Desktop Processor And here's my GPU: EVGA 02G-P4-2670-KR GeForce GTX 670 2GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card Now, I'm looking at upgrading the GPU to something with a bit more oomph, so I can stream better content. Since I have the cash to do it, I've been considering going to a GTX 970 SLI (2x) setup, but I'd like to get some feedback from anyone with similar or better cards. Before anyone mentions it, I would prefer to go with Nvidia, simply because I have had awful luck with Radeon cards in the past...I've never had one go more than 6 months without having some critical error that bricked the board, and even though they've covered it under warranty every time, it's been aggravating...and it's killed my interest in them over the years. That said, if you can give me a good enough reason (with stats to back it up), I'd consider it. So...thoughts?
