What Mobo do you have? I would be surprised if its impossible for you to use an ATI card, and I really would suggest a 5750 or 4850 way over a GTS 250 as they're all on a similar level performance wise, and the 4850 is way cheaper(you can get them under $100), and the 5750 has DX11 and eyefinity. If you are stuck with one of those Nvidia cards, I would get the MSI since its got a smaller MIR, so a better price up front.
Thank for the reply. I have a older Sony VGC-RB30 http://www.docs.sony.com/release/specs/VGCRB30_mksp.pdf
As far as I figured out the MOBO is some kind of a Intel D915GAG. I say some kind, because it was made for SONY.
I have tried a ATI 5770 in the computer but after that the computer refused to boot at all. When I pulled it, everything was fine. I have to mention that I upgraded the PSU to 500W and I have 2GB RAM. So I did some research on the web and found in several forums reports about the same issue - no booting with the 5xxx ATI cards. The problem seems to be PCI-e (even if it's stated that PCI-e 2.1 - should be down compatible). I also found some reports on this forum with the 5750. So I don't want to run in that problem again and I'm afraid that the same things will happen with a ATI 48XX. I just want to upgrade my onboard graphics.
Yeah- I can understand that. Just so you know- if you can order from newegg, if you have problems, just call them up and they'll refund you and pay the shipping back, so its a no issue type try if you feel like giving the 5xxx series another go- could be you just had a card that wasn't working right. The other thing I would suggest is see if you have a friend who has an ATI card that you can just borrow, try out, and then give back. If it works, you are good to go, if not, then you know for sure. I wouldn't give up on it just because you had one card that didn't work;-)
MIR don't mean you'll never see it. you just have to be patient and willing to wait for it. I've always gotten every MIR I've ever sent in, just takes a while. Just gotta be careful to fill everything out right and be patient till it shows up.
