Entry level OpenCL

Hello,

I have two applications I want to run on GPU's but neither require double precision floating point arithmetic. But, who knows what I might need a few months from now.

For now, should I just buy a lower end 5xxx series, and then if I have the need, step up to the 58xx later, when prices will have presumably come down?

Two 400 stream processors still aren't as much as one 1120. Maybe I should get the cheapest 1120, doubling them at some point for 2240. But then I'm back to the double-precision question again.

Maybe low end double precision should drive the decision, eliminating any need to upgrade for the coming 2 years?

Other considerations are a new 27" LG HDTV ready monitor, and the ability to run one or two more 22's.
(Someday I might hook up 3 to play Aces High II in Eyefinity mode)

Gaming is a low priority. I'll probably get my old Aces High II account re-established for 30 days just to try it out. I have an X800 now, so anything will be a major improvement there.

well first what is your budget?

5770 or a 5830 wouldn't be a bad choice but I can only recommend them on price and performance. If you are able to afford it and you are doing time sensitive work either as a student or a professional a 5850 or a GTX470 would be good choice.

Thanks. My data sets will only be big enough to gauge performance, so spending extra on a card that will do the work a lot quicker may not be necessary. I'd rather put the money into some other items. My Newegg wishlist is hovering just under $1K, and I'd like to keep it about 800-900 total, if I spend more on one item, I have to skimp somewhere else.

Lets see if I can paste it in here:

As you can see, I could use another 4gb of RAM. I might be spending more on the mobo than I should. I spent a lot of time looking at 790FX, 790GX, 890FX, and 890GX. I think I chose the one I did because it supported 1600 memory, and I thought that might be better for a future, faster CPU. I can't find much in the way of 6GB sata drives or usb 3.0 devices, so I'm not sure why I'd need those. The 27" display is extravagant for me, which is rare, but I want one!

**oops** I forgot, I use several flavors of Linux -primarily Ubuntu 10.04, I have a copy of XP I run in a virtual machine when needed.

Nice choice of parts. I have that psu and its ok but not the highest quality ended up modding mine.

What did you do to it? I don't know much about things like that, but it's the sort of thing I'd try if I had a good tutorial, and no downside.

Simple but ugly, I took a spare fan and suspended it with bread ties at the rear of the psu outside the case to draw air out. The stock fan doesn't run at full speed and the unit does get quit warm.
