Hey RS comp guru's

I'm having an issue trying to split one DVI source to two displays.

Before I begin here's the specs:
Win 7 64
Q6600
4 Gig Ram
Asus P5K
9800GTX (has two dvi's)

So the story goes, I'm already running dual display (extended desktop) so the two existing DVI ports are used. What I want to do is split the MAIN display (26" 1900x1200) to my LCD TV(46" 1080P). Seems simple enough so I bought a DVI Splitter cable and a long ass DVI to HDMI cable. Big nono on Vista and ended up crashing my comp and me having to do a system restore and spend hours trying to recover my data. So now I'm running Win 7 and decided to try again, so it doesn't crash the comp but when I plug in the cable to the TV the secondary monitor becomes the main monitor and the main monitor stays off. I looked into it a little further, but apparently I can't run two different resolutions (or even one common res) off that adapter.

I looked into a DVI switcher...they cost $300+...Not worth it.
I can't run SLI because the card is too old and the mobo is crossfire
I did a little research today and found a USB to DVI adapter but not sure if that's the best alternative.
video cards w DVI start around $30-40 but I'm not sure if that'll work.

SOOOOOO does anyone have any input or suggestions?

Can i technically run a different 2nd video card without complications?

I know it's long winded but thanks for reading guys
