Heres a 8600 with 1GB of ram.
60$, theres a non open box version for about 20 more.
Thanks, I'll see about checking that card out with the others. With Compiz, putting a 1080p video on the surface of a 3D object isn't uncommon, so the card has to have a bit of power behind it ^_^. That being said, if it works, it works.
Are you trying to decode video at 1000FPS or something?AireTamStorm said:I've actually benched several cards in person, including the 8600. (Also did an 8800 GTS card) Didn't cut it... in the memory department. I know it is slightly ridiculous, but I figured putting top-end cards in the thing with plenty of VRAM (Compiz, the texture sizes are quite different than in a game) and GPU power would help a bit. If there was a good 8800GT with 1GB of VRAM or a Quadro with quad head support that wasn't $2,000 I'd go one of those routes. That and I did mention CUDA development (I don't know if there is an ATI equivalent).

No, but there are applications coming out mid next year to transcode video on the GPU, which would be beneficial for one of my web sites. The screens at 1680x1050 a piece, and theres going to be two per card. That is alot of pixels to render even at 30FPS, let alone my target 60-80.
It is pretty much decided that I'll either use GTX 280's or GTX 260's at this point... I want all my bases covered and money isn't really a problem. The 260's are considerably cheaper, however, which would allow me to perhaps get some nicer screens or other accessories. Problems now are, reliable and quick storage, power (although not so much thanks to Chip), and bus speed.
I'm so far decidedly on AMD, because I think that HyperTransport bus will be extremely beneficial to the four cards. This is where AMD still has Intel owned, although even my current Q6600 outdoes the Phenom I'm thinking of buying. Would an Opteron be a better CPU in terms of processing power? Or am I not going to have to worry about the bus bandwidth, and possibly go the Intel route?
Finally, this kinda turned into a thread about my rig, I was somewhat hoping we could discuss others as well.
waffles said:That makes sense, a 4 280s would fly for h.264 encoding.
Yeah, I'm just hoping I'll be able to use all four simultaneously (it may be limited to one card per transcode).
From what I've seen, Intel is the higher end at this point, but you pay double for comparable performance. What are you buying the rig for, gaming, work? For playing video, Intel CPUs perform better processing power wise, but the AMD HT bus is going to allow you do download stuff, copy files between hard drives, etc while watching that video with a little more difficulty per core, but much easier for the bus. If you're going to do Crossfire or SLI that bus helps quite a bit in certain applications too.waffles said:...
Could anyone recommend wether or not to go with AMD or Intel processors? I probably wont do much overclocking.
Gaming, Intel is the way to go as long as you can afford it. If you're building on a budget then AMD will give you comparable performance for half the cost.
waffles said:Im hoping to build something capable of playing a decent amount of games (crysis on high at a decent fps) for around 850,
From what I hear, 850 + high = good luck. Unless of course they were referring to the "Ultra" setting, if there is one.
waffles said:Im probably going to use it for general computer stuff (video converting, music playing, etc.)
Then why the crysis referral? That will hardly bench any of the stuff you mentioned.
waffles said:If i can get comparable performance for less, i would probably go with AMD, as i definetly wont be in the super high end range of things.
If you look at the prices on NewEgg, thats is the tradition. Its been that way since my friend built a Barton 3000+ / Radeon 9800 Pro machine (~$700) and I built my P4 / 5950 Ultra machine ($1200) to see 5FPS of additional performance in Doom III. AMD + nVIDIA makes a nice balance for most of the rigs I've built for friends.
waffles said:Also, any thoughts on dedicated sound cards/dual core vs quad?
Let me put it this way: When I had my P4 (1 core), I could bring the chip to its knees in Compiz, with a 1080p video. An AMD X2 (and admittedly a card upgrade), It took 3 videos simultaneously to bring the CPU down. Quad core Intel? I couldn't make the CPU choke, no matter how hard I tried. And at 8 videos I finally saw the hard drives actually weren't able to keep up with all the seeking. Quad core, for pretty much any application other than gaming, is the way to go.
