if you are serious about your CAD, ditch the gaming card and get a quadro. I got a quadro fx1800 on my build (i7 920, 12g RAM) and it plays games fine unless you are a graphics junkie. I'm an architecture student and after doing a lot of reading, I determined that it was worth spending the money on the quadro. Might be different for you, because I'm using different programs - Revit, AutoCAD, 3DS Max, and Photoshop.
I am currently downloading crysis so I'll let you know later how that runs, but I can tell you for sure that it runs Farcry 2 cranked almost all the way up on 1680x1050 resolution just fine.
Not sure which would give me more benefit speed or timing or a combination of both
I did look at the USB3/SATA 6 boards and decided the extra price wasn’t worth it, I am unlikely to upgrade the HD to ever need SATA 6 and the only thing I have plugged into my usb port is a printer which is 7 or more years old and an MP3 player
Think I’ll go with the 5870, I looked at workstation GPU’s and decided it’s not worth it for now for the amount of CAD work I’m currently doing, at the moment I’m using an E6600, GTX260 and 2 gig of mem and it’s not too bad. Will consider a workstation GPU if my work picks up maybe in 2011
The Thermalright Cogage TRUE Spirit - $45 is on special and got good reviews and the Coolermaster Hyper 212 is an extra $20 more. Will check prices on the day that I buy, both seem to be able to perform quite well for what I want.
