xfx 6800 gs

[Destroyer^]

do these have any pipes to unlock? do they use 12 or 16 pipelines?

[sawyen]

no, they dun unlock.. and needlessly really.. the GS clocks so high that it covers its 4pp deficit against an ULTRA.

it came pre o/c to 485mhz 1.2ghz eff but ahd to tune it down to 450 mhz 1.1 cuz it wasnt working properly

scan are doing a 6800gt at a lower price than some of the 6800gs cards though

i got mine for 139 quid xfx 6800 gs lowest i saw was 160-170 for gt

I've heard that some AGP XFX 6800GS have pipes to unlock, but for pci-e version, forget. But overclock is enough to put this card having a 6800Ultra performance.

Unlucky yours wont clock as high.. But if you could (for some reason) get it to like 520ish/1250ish.. you're pretty much at around 440/1200 on Ultra..

The PCIe ones certainly don't unlock - they are a new fabrication at a smaller 110nm process (compared to 130nm for the GT). They are also natively PCIe unlike the GT which is AGP-PCIe bridged (not that that makes any difference).

But the smaller process means they clock very well bringing them up to the same performance as a GT.

Scan do stock GTs quite cheaply, especially on offer (I got mine for around 153) but I made that decision more on noise than performance - that and I don't want to overclock yet.
