I can get the AGP XFX 6800 Xtreme 512mb (DDR 3) for $58 second hand.
I live in South-Africa and it is a good deal around here. I want to know if would be worthwile spending this money on my current PC. I plan to overclock the graphics card from 350/1000 to 425/1100 .
I think I have damaged the 6600 though with a overclocking attemp (My friend said it was the 6600 GT and I read lotsa reviews on what people overclocked that card to and so I overclocked my poor 6600 to that and from that time It crashes and gives me artifacs). I also have a spare radeon 9250 which I have used for many years and I believe that card is used up because Im getting artifacts at stock speed (under clocking that at the moment), btw I have not overclocked the radeon 9250.
I must still find the right clock speeds to underclock my 6600 to for it not to crash anymore.
All my friends are telling me not to waste my money on a graphics card for this PC but I want to pass this 1st pc of mine along to my little brother in a year and it would nice if I can give him a "balanced PC" .
the 6800 Extreme is a lot of improvement over the 6600( twice the bandwidth and twice the M/textels per second), but if you have damaged the card, well how long do you think it will last, as for OCing, that seems like a big jump, it is a extreme edition so I would guess it' OCed already(are you sure you want to do that) but then you are using older hardware and I never OCed AGP graphic cards, yes you are not going anywhere fast with that computer, how much life do you think it has in it really
I think I didn't damage the 6600 after all.
I believe I were getting instability problems because I overclocked my AGP bus to 85mhz with ClockGen when I was overclocking my CPU.
The XFX Extreme 6800 is based on the 6800 XT I believe according to what I have read.
Therefore it also have 8 pixel pipelines.
Like you have said it does have double the bandwith 128bit vs 256bit.
The other difference is the memory (speed and size)
The 6600 is 300/550 at stock vs 350/1000.
I have decided to stick with the 6600 because it seems not to be damanged.
If it turns out to be damaged indeed, then I don't think If I will be happy with an underclocked radeon 9250.
I know that the life is ebbing away from this PC.
I dont want to let go of my faithful friend though.
I am still running windows xp.
Do you think I should upgrade to windows 7 or will windows 7 eat to much of my ram and cpu making my computer abit slower for general use and games I might want to play.
