Quad Crossfire coming soon from ASUS and Gigabyte
We have all seen the dual chip Geforce 7800GT graphic card from Asus, and they are even selling a limited amount. Asus is working on putting two ATI chips on one PCB as well and this time it will cover the X1600, X1800 and X1900 GPUs. By having two "dual GPU" graphic cards a "Quad Crossfire" will be possible. To make this even more interesting, this time the user has four monitor connections on the board. Gigabyte will be presenting their version of two ATI GPUs on one PCB in the near future as well.

All others, keep your comments to yourselves. It makes you look just as bad when you come back at them. Tell a mod/admin and they will take care of it.
And I'm sick of people telling others to "STFU" too. Next person I see tell some one else to "STFU" will have a nice vacation.
I should close this thread now... but I wont. Next comment that is at all out of line from any of you, thread will be closed and you'll be dealt with.

Lets start with the basics...
- Bit = 1 Binary digit
- Nibble = 4 Bits
- Byte = 8 Bits
- b = Bit
- B = Byte
- Mb = MegaBit
- MB = MegaByte
- Gb = GigaBit
- GB = GigaByte
- So on and so forth...
Prefixes:- Kilo = 10^3
- Mega = 10^6
- Giga = 10^9
- Tera = 10^12
- Peta = 10^15
- Exa = 10^18
- Zetta = 10^21
- Yotta (Looked that one up :)) = 10^24
But don't forget the "24" in the 1024... it's not a 1000 Bytes in a KiloByte, it's 1024 Bytes. (this is why a 200GB hard drive shows up as 186GB due to the "24" being dropped)Now PCI-E comes in 1x, 2x, 4x, 8x, 16x, and 32x. These number are the amount of lanes, not times faster than AGP and what not.
- PCI-E 16x = 16 lanes.
- 1 lane = 2.5Gb/s (GigaBits) or ~250MB/s
- 16 lanes (16x) = 40Gb/s (GigaBits)
- 40Gb/s = ~4000MB/s
- PCI-E is full duplex so it has two directions, and you double the bandwidth. A lane is up/down stream.
- PCI-E 16x = ~8000MB/s (upstream, downstream)
- 8000MB/s = ~8GB/s
Calculations above are rounded to save time and to just give a general idea.Thanks to DantheBanjoman as well for checking this over and picking out my typos.

as far as i know theoretically the agp8x bandwidth limit has not been reached. agp4x definatly has but not 8x. these cards should yeild some insane performance numbers but its not really worth the cost. either way this is a beautiful peice of tech.
As for quad SLI/crossfire, those techs are quite pointless to begin with for the average user. Unless you can afford 2 high end cards it's not for you. A single high end card would be much better than 2 low/mid end cards so these aren't an option either.

and as cool as these cards are im seriously thinking of switching over to nvidia for a gen or 2 as agp is the only thing im going to be having for a while (and it was givin to me by a freind of mine who whanted to save me from pci sooo) so im seriously considering a 6800gs so i can mod it and it beats my 9800pro.
