Hi guys quick uber noobish question. I have just bought a XFX 7800GT (gotta love the special deals) but I noticed it only has DVI connectors, both my monitors are crt that only have VGA connectors, I notice that it comes with dongles, do these go from dvi to vga well (or at all even) or have I just maxed my credit card (cos bought a new system along with it) only to have no screen?
