Tough decision between cards

post #1 of 9
Thread Starter 
My friend decided he wanted to play some games on his computer....I had some old graphics cards lying around. He currently has this card http://www.newegg.com/Product/Produc...82E16814130292

And I replaced it with this card http://www.newegg.com/Product/Produc...82E16814130267

Before I give it back to him, was this even an upgrade? I know the 8600 is newer and all but it has DDR2 128 bit vs. DDR3 256 bit. He just wants to play some older games like FEAR, WC3, etc. And I know the 8600 supports DX10 but he wants to stay on XP so won't have to worry about that

8600 is faster and has more video memory.

The 8600GT should outperform that 6800GS, regardless of it only having a 128bit interface, the 6800 GS is still using Pixel Pipelines.

The 8600 GT has 32 Stream Processors, this makes it better overall.

Damn...So in this case benchmarks are not accurate? Cause the 6800 benchmarks higher

It's more likely that His processor was bottlenecking that 8600GT, And when you threw the 6800GS In, It leveled it out. So, If your benching Higher on his PC, Keep the 6800GS, because having a balanced system is Key to gaming performance. But, You can always Overclock His processor and Keep the 8600GT 512MB, being able to throw more buffer at higher quality, and more demanding games. So, My final decision is That You just Overclock his Processor (Getting a new heatsink, if the one he currently has is crappy.) and Keep the 8600 GT.


Hope that helps you and your friend. Getting a really good quality heatsink Won't be that pricey, If unless It's a Socket 478, or a Socket 754 Motherboard. IF it's like a Pentium 4 775, You can Surely Overclock With a Cooler Master Hyper TX3, Or If it's a socket 939, 940, Or Socket AM2 AMD Athlon 64, You can Overclock pretty well too.

I'm curious what benchmark and how different are the results? I would choose the 8600gt. Dunno if I ever tried a DDR2 version, but I would think a 6800gs would be closer to a 8500gt.

He actually has a decent processor. It's a Celeron Dual-core E3300. Unfortunately it has a stock cooler and the mobo doesn't have any overclocking features (I wish it did) Thanks for the reply

Passmark Performance test. This 6800 originally replaced an 8500GT in another computer a while back. The 8500 was pathetic, only being able to play Crysis on low @ 1024x768, and the 6800 GS could play Crysis on Low @ 1440x900

I originally thought, and never ruled out the possibility at least in my head, that, the difference in SP on card A vs the PP on card B might not be enough to attain faster or = speeds with a lower memory interface.

I don't have an exact amount, but, I remember when PCI-E first came out and SP were being discussed as the new "amazing thing" Nvidia devs said something along the lines of 1 SP = 4PP, or something like that, I know it was at least a ratio of 1:2

Also, depending on the resolution your friend's going to play at, a 256mb framebuffer would cause issues. We need to know what resolution he plays games at, also, another important aspect is does he play at non native resolutions too as this affects the response. Even in FEAR, 1080p would definitely go past 256, but, what I can't comment on is if the higher Vram would offer more performance with a lower memory interface than the 256 with a higher memory interface. Now, having said that, I can say that if the settings your friend chose to play at went past a 256mb framebuffer it would significantly decrease performance as the card has to start using the HDD/Pagefile as texture ram.
