Looking for yet another Quad Video Card

[Jabba]

So far I have bought the following quad output video cards.

Matrox 200MMS (£420) 1997 2D performance only...totally CRAP but the only choice at the time.

Xentera GT4 AGP...(£450) Excellent card...good 3D performance and can run at 1600x1200 DVI...absolutely perfect for me....one problem...the first one I had lasted about one month...then the output to monitor four failed...colorgraphic sent me a new card...that lasted about two days...before monitors one and two failed....

No idea what is causing the cards to fail...maybe the overclocking from 3.4 ghz to 4.02 ???? maybe a faulty PSU ??? anyway...I am without a main system yet again....

The only other decent card I have seen is the Parhelia HR256 from matrox....£1425.00 though for a graphics card...that needs some serious research before a purchase...

Have anyone got any ideas on two separate graphic cards with dual DVI outputs on the same system...I guess one would have to be AGP the other PCI...or would two PCI cards be better ??

I know XP supports multiple video cards for multiple monitors...but sadly I can find no information on anyone that runs such a system and what performance you could expect from such a configuration....

Any ideas and advice please ???
