4850 Cf

[Sanada]

I'm going to build a new PC soon and want to either get a single 4870 or two 4850 in CF. I wasn't going to bother with CF/SLi but the benchmarks for two 4850 make it look like a worth while investment. My main problem though is I'm trying to do this in a HTPC style case. From what I've heard, the cards are around 9'5 inches long. There is JUST enough space but I can remove the HDD cradle if need be to create a lot more space so this shouldn't be an issue. The HDD can go in the spare 5'25 bay with a mount. I think my PSU will cope OK. It's a Tagan TG500-BZ (500W).

Another problem is heat build-up. I've heard people say they've had problems with heat build-up in HTPC cases due to poor air circulation. My case is a Silvberstone GD01S-MXR. Would water be an solution? I'd rather not bother with it though as it's more tedious to install and maintain while being much more expensive.

Also, could someone recommend me a good HDD? I just need something that's around 250-320GB and quite fast. I don't need so much space as I'll never use it all and I have two external drives to store stuff like music, videos, etc. I'd rather sacrifice space for speed. I was thinking of getting a VelociRaptor but they're a bit pricey here (like 200 pounds, UK).

Since you are putting it in a small case I would go for the 1 card solution. Plus the coolers on the 4870 exhaust out the back of the case while the 4850's standard cooler just keeps the hot air in the case. Which is even worse in a small case (less air flow etc). That is unless you have a 24" LCD with a really high resolution to maintain in games.

After succeeding with the hardware installations, you'll have to deal with cable management and heat.
My Antec 900 wasn't spacey enough for my SLI setup, and though ignoring the fact for a while, I finally end up buying Antec 1200.

Think about full tower, those cards will generate lot of heat, quite literally.

Good Luck.

I've look around and it seems my PSU could cope with two 4850's in CF but the heats gonna be a problem it seems. My monitor is 21" with a 1680x1050 max res so I guess there potential will be wasted. Think I'll get the single 4870.

Thanks for the help guys.
