I'm a relative novice when it comes to this sort of thing so I'd much appreciate the kind of feedback a toddler might get if he were upgrading his computer with a new graphics card. I got myself a GeForce GTX 570, but, not knowing a thing about how machines use power, didn't realise it required its own power source. My loose understanding has led me to understand my machine has a couple of loose AGP/Molex cables (I think - there are several loose four-pin connections in the machine that don't appear to lead anywhere but match the image in the graphics cards' manual), but the card requires two PCI-Express 6-pin connections. I understand adapters can be obtained to get around this, but I hear there's some no-nos about doing this with regards to how you route the power. Can anyone give me a dummy's guide-to on solving this? Happy to provide any further details that are within my limited knowledge.
