Alright, so my power supply has three PCI-E connectors. My 4870 takes up two, but I want to get another.. I used an adapter on my GTX 280 when I had my Antec 500w and it worked fine. I was just wondering if it would be worth it to use the adapter or just get a HD 4850 1gb?

Well the old 3 wire ones(now banned)started fires. Yet they were cool because you could use more powerful cards with lower watt PSUs for some fed up reason.....

The others it doesn't really matter. Hell you could make one:)

Alright so the one that came with the card will work fine? I'm still debating on whether or not to do it. It's this or a cooler master haf.. The haf would last me longer since I upgrade my cards like every other month lol

Im looking at the cooler, and there is the 1GB model, I do believe however the 4870 can drive the 2GB ram where the 9800GTX cant
