So I was looking at the GTX 770, and people saying they had problems with powering it properly if they didn't have a single 12V rail with at least 42 amps. My current PSU has several of them at 22 or 25 or so amps. So, I figure, ok, I'll get a new one, make sure I'm well in the clear with wattage, single rail, 12V@56A, looks good.
Let's compare the 770 to the 560 I bought. Oh, look, it uses PCIe 3.0 where the old one uses 2... Hmm. I check the motherboard.
2 x PCI Express 3.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4), or dual at x8 (PCIE2) / x8 (PCIE4)) (PCI Express 3.0 with Intel Ivy Bridge CPU, PCI Express 2.0 with Intel Sandy Bridge CPU)
Huh... I check-- Yeah, my processor is sandy bridge.
So...
1) My processor is sandy bridge
2) My motherboard says it uses PCIe 3.0 with Ivy Bridge and PCIe 2.0 with Sandy Bridge
3) My planned graphics card uses PCIe 3.0
If this means what I think it means, I'm going to end up replacing everything but my hard drives and the case.
Is my budget forgeted?
