Running usual 2x dell 2007fp in portrait @ 1600 x 1200 with a 30" landscape @ 2560 x 1600 in the middle.
Got two choices
1. Can run 3 monitors off newish Radeon HD6850 1Gb DDR5 (DVI-D, DVI-D, DP, HDMI). Need to buy DP to DVI-D active adapter (no DP on 30")
which is...
2. Same price as Radeon HD5450 1Gb DDR3 (DVI-D, HDMI, VGA)
Got a 750w Modular PSU and 2x PCIE slots so thinking I have power and bay space to run two cards rather than a converter cable. May add HDMI TV so may benefit from the extra output with two cards(?).
Planning on hooking 1x 2007fp and 30" to the HD6850 and 1x 2007 to the HD5450 all by DVI-D.
Anyone foresee any thing catching fire / frying if i go for the two card option?
Thanks in advance

My PC guy (who was very good) tried all sorts of stuff and couldn't get it going.
I'm just about to have the card replaced with 2 x nVidia cards so I can run all 3 monitors on DVI without an adapter. Your PC won't catch on fire (lol). 2 x cards is common. My old PC had 2 x entry level nVidia cards and they worked perfectly.
I had a disgusting situation over the weekend where I had to set up a PC to go with 2 x 30" Dell monitors, the graphics card I had was the Radeon 7970 which had 1 x DVI-D, 1 x HDMI, 2 x Mini DP.
It wasn't originally the card I wanted to use as it doesn't have 2 x DVI-D but it said it comes with adapters for HMDI to DVI and Mini-DP to DVI so I figured that'll be OK.
The plan was to have both monitors do 2560 x 1600 but that didn't happen! Only one of the monitors getting a very crisp 2560 x 1600 as it was plugged in with DVI-D whilst the other one was going at 1600 x 1200 when I used DP mini to DVI adapter.
When I used the HMDI to DVI adapter it would reach 1920 x 1080 which wasn't good as the aspect ratio was screwed, I then got a HDMI cable to plug it to go 1920 x 1200. Against it wasn't acceptable.
When I plugged in a 30" Apple monitor via the mini DP port (it required a USB too) it displayed 2560 x 1600 with no problems.
I know the graphics card isn't the issue so it looks like I just need to get a mini DP to Display Port from Amazon and the misery will be over.
Very surprised the adapters limit the output to 1600 x 1200, if I wanted that resolution I'd buy a few 20" monitors lol.
I have to say, 3 x 30" Monitors is sick!
