Regardless of how good or bad xbench is at GPU scoring it's isn't going to make AGP2x the same speed or faster if it's in fact slower.
I simply don't like people that try to act like they know what they are saying. It's misleading advice when you just state specs.
If it gives the same EXACT SCORE for a graphics card that is 4 times better, why would you think its good at rating AGP 2X vs AGP 4X? That is non-sense.
It looks like Xbench just finds the model in its database and throws in the rating of the stock AGP card. That would not be the first bench to do this.
If you don't like people that try to act like they know what they are saying, I don't either. Who likes that anyways?
On my side, I don't like when people boast about their experience and stuff... The reason why you seem to think I know nothing is because as I write, I expect the reader to be bright enough to interpret the facts, using his own knowledge. In other words, what pisses me off is people that talk to others like if they were total noobs, so I'm not doing it with you.
It's up to you to think I'm stupid, or trust the infos and investigate. It would be useful to get a more reliable bench for AGP graphics. It is also up to you to test different AGP cards and see what happens. That way we could see where the problem is. Maybe Xbench just gets the stock info for GPU, maybe theres an issue with some cards... , maybe it's just with the 8X cards, or the flashed pc cards, or ... etc.
edit: as I said, 2X AGP vs 4X AGP will NOT make a difference if the card the OP is using doesn't come close to saturating the bus. However, a 7800 GS like mine will, and as people have reported, it can even come close to saturate an 8X AGP bus. Google it if you don't trust.
--->>>So the advice would be... if you plan to play Doom 3 or Quake 4 at decent quality and FPS, definitely stay away from 2X AGP. If not, I guess it doesn't really matter.
