I've been looking over the Samsung 23" LED Syncmaster S23A750D, a 120hz TN monitor. It has two ports, one for an HDMI cable and another for a DisplayPort cable. It can only run in 60hz if you use and HDMI cable.

The problem is that the graphics card I'm going to buy doesn't have a DisplayPort connector but it does have two mini DisplayPort connectors. So I'm wondering wether or not the monitor will be able to run in 120hz if use a mini DisplayPort to DisplayPort cable instead of a regular DisplayPort cable.

Any got a clue?

I've decided to build myself a new PC but I'm having a really hard time deciding which graphics card to get. It seems the HD 6970 is a pretty formidable card, especially in a CrossFire setup. I've been doing some research though and the HD 6970 is apparently a pretty hot running card, especially in a CrossFire setup since there usually isn't enough space between the cards for decent airflow to get through. So I have a few questions about the HD 6970:

Will I be needing a case with really good airflow? Must I therefore avoid especially silent cases?

Will I need to buy a bunch of extra fans, and if so, how many? Is there even a point to run these cards in CrossFire without water cooling?

Are there manufacturers that sell extra thin 6970's or socket 1155 motherboards with handsomely spaced PCI-e slots for a decent price?

Also, what wattage is recommended for a 6970 SLI setup?

Unfortunately, it didn't work. I used Driver Sweeper and deleted all Nvidia display and PhysX files. I restarted my PC and installed the new drivers. As soon the installation was complete, my screen was covered with white and black stripes. I rebooted and as soon as it said windows starting up, my screen went black. Oh well, any other suggestions?

Will try that immediately, thanks.

So my network card drivers is probably not the problem then. Thanks.

The problem is if I do this, it removes my drivers for my network card, and after I re-install them I'll be right back where I am now. I will check if there's any other old Nvidia files I might have missed though, thanks.

So I upgraded my GPU and PSU a few days ago, from a NVIDIA GeForce GT120 1GB to a Sapphire Radeon HD 5670 512MB. The problem is I can't update my graphics drivers without my screen going black. The computer is still turned on and i can reboot, i can also change desktop resolution, but that's about it. If I try to do anything else my screen goes black, sometimes with white stripes. My computer works fine if I only use the drivers that came with the card, but there are a lot of games that will not start unless (Im guessing) update my drivers. Also, since I have an NVIDIA nForce 630i motherboard, I don't think I can remove all of the NVIDIA files since I couldn't connect to the Internet last time i did that, which I read and was told is important before you upgrade to a new graphics card. If there's any relevant information Im leaving out or you would like to know, please just ask. Greatly appreciate any suggestions on things that may help.

Alright, the few reviews i found said it was a good enough PSU. Again thank you so much for your help!

Damn, I have no idea what brand my PSU is, probably some crappy brand though. How much power would I need to be safe? Would a PSU with 450W and with the 80+ thing from Fractal design be good enough? Do you know if Fractal Design are any good?
