Hi. I have a MP 4,1 with a ATI 5870. I have a GTX 650 that I want to install. If I wanted to keep both, what's the best way to power the new video card? Would this splitter do the job? http://www.amazon.com/StarTech-com-...0374781&sr=8-5&keywords=pci+power+cable+6+pin Any advice/comments regarding whether I should just pick one and ditch the other would be appreciated too. My ultimate goal is to push 4K content unto my new TV. My understanding is the ATI 5870 cannot handle 4K but I should be able to with the GTX 650. I think the GTX 650 could handle both my computer monitor and the TV but it doesn't support the Apple boot screen. Please correct me if my understanding is off. Thanks in advance!
