GTX 280 versus Radeon 4870: DVI signal strength/quality?

[DRavisher]

At present I am using a Radeon HD 2900XT with a HP LP3065 display (30", 2560x1600) with a 10 m (32.8 feet) dual-link DVI-cable. I know that a lot of nivida cards struggled with DVI signal quality back in the FX days, but I haven't read any more about this since then. Since I am pushing the DVI spec by quite a bit, I was wondering if anyone has any knowledge on this issue. Assuming AMD hasn't changed their TMDS transmitter much since 2900XT I am guessing that the 4870 should work just as well, but if nvidia's transmitter is just slightly worse than AMD's I could be in trouble.

While buying a DVI repeater would be an option, that would push the total price of the GTX 280 up a bit too high compared to the 4870 for my taste.

Any thoughts?

With those kind of lengths you might as well use a CAT5 repeater

I don't know what you mean with a CAT5 repeater (wouldn't that be a network thing?), but the idea is for me to be able to use my currently laid cable with my new graphics card. If I have to go for a DVI repeater when I switch to nvidia the cost is just too high compared to what AMD has to offer.
