Xfx radeon 4850 problems running dual monitors

I hooked up a 24" samsung syncmaster and a 23" acer monitor to my xfx radeon 4850 card and at first it worked as it should. I could spread my windows to each monitor and watch videos in one and read whatever in the other. Then the card started crashing. I tried to use the catalyst control center to no avail. The mobo accelerater hardware does not recognize the xfx card. I tried smart doctor but it did not recognize either. Now if I pull a window into the secondary monitor I lose my mouse and must wait till it loads up. I am using an Asus P6T mobo with 12 gigs of memory and a core i7 processor. A corsair 750 psu. Should not be robbing me of power. The card has 512 megabytes of DDR. It worked well with one monitor. If I was to upgrade the card to fix this problem does anyone have any suggestions as to the best card in the 300 dollar range.

What i7 are you currently using and do you have a preference to what brand you would like and chip maker? Also could you fill out your system specs for me please.

System Setup:
CPU: i7 (fill in the blank)
Memory: 12 gigs (Tri channel?)
PSU: Corsair 750w (TX,HX?)
Video Card: 4850 however WiP

I suppose I would consider an Asus graphics card so I could use the EPU six engine. It does not recognize the xfx card so I use ccc. I also have turbo V. Am not familiar with any of this stuff. Just want to plug and play.

ASUS P6T Motherboard
Intel Core i7 920 Processor BX80601920 - 2.66GHz, LGA 1366, 4.8GT/s QPI, 8MB L3 Cache,
2 Corsair XMS3 TR3X6G1600C8 6GB Memory Module - PC12800, DDR3, 1600MHz, DIMM
Radeon HD 4850 512MB GDDR3 PCI Express 2.0 x 16

Okay so it does look like you are using a tri channel configuration and its a x58 chipset. Best card in that range for you hmm I'm not sure I would say a 660Ti, or a 7870 for you. Beyond that I would think you would want to do some overclocking to your CPU.

And ASUS isn't a bad way to go brand wise the 660Ti is stronger then the 7870 as a note.

No problem. So you went with the factory overclocked one right on. It should serve as a great card for you. Hope you are happy with it. I have a 670 which is the 660Ti's bigger brother. You should let me know how it goes :)

Asus 660 is working fine. Pushing a 23 and 24 inch screen. The old card xfx 4850 was working great on a single monitor when I pulled it. Try to use two and it would slow as soon as I pulled a tab to the other screen.
