I have an ASRock 775 dual VSTA board with both AGP and PCIe slots. Currently using AGP with an ATI 9800SE. Time to move up a bit to a PCIe card. However, I have seen conflicting info on this board's PCIe slot. It is either 4x or 16x. My question is - If it is 4x does that make a material difference?Regards,Dick BoleyA PC, an LCD, speakers, CH yoke

hmmm, I thought all the video cards were either 8x or 16x....I think 4x is the little one....

HelloI am moving from an AGP X850XT which is having problems to a PCI-e X1950 Pro on my ASROCK 4CORE-VSTA.I am also swapping my DDR PC3200 memory for DDR2 6400 sticksMy own opinion is that the 4X PCI-e wont be a handicap but i will post back later in the week with my findings.I picked up a cheap X1950pro on EBay while i wait for confirmation that the ASROCK 4CORE-VSTA will work with the new ATI 3850 boards.This has been a really nice M/B for the price.

HelloAsorock 755 Dual and also the 4Core-VSTA have a 8X AGP slot as well as a 4X PCI-e slot, they also take either DDR or DDR2 memoryThey are a great board for anyone upgrading in stages, mine has been rock solid with a E6600 and a AGP ATI X850XT and 2gb DDR PC3200http://www.freewebs.com/reading1871/30.jpg

I reckon it will be like AGP 2x/4x/8x was - nice theoretical performance and throughput differences, but neglible impact to real game performance.Gary

Remember, these are just the busses . . . the tracks that race cars run on. The Vcard is the "race car" that uses the PCI-e "track," the ram modules and CPU are the "race cars" use the Front Side Buss "Track" and the harddrive uses the SATA "Track." For instance a typical hardrive can transfer data at 50-100 MB/sec these days. A SATAII buss can facilitate transfer rates up to 375MB/s (aka 3Gb/s). This fast SATA buss provides No additional speed advantage to the HD. In this case the capability is limited by the HD, not the buss.And so it goes with Vcards PCI-e and the system FSB/Hypertransport Busses.Asus had a mobo set to split the 16 lane PCI-e into two, 8X Vcard PCI-e busses. This was to accommodate a crossfire setup. It appears that 16 lanes of PCI-e racetrack is at least twice what ANY Vcard has the capacity to use.If you're really interested: http://en.wikipedia.org/wiki/List_of_devic...#Computer_busesPCI-e provides a data transfer capacity of 250MB/s per lane. AGP provides a data transfer capacity of 266MB/s per "X."That means AGP 8X provides more capacity than Asus' PCI-e 8-Lane per Vcard buss setup. Even today, an AGP 8x buss would provide entirely adequate capacity for a modern Crossfire Vcard setup. And now we have PCI-e 2.0? Geeze! Intel wants to sell us the Brooklyn Bridge.PCI-e /16 provides 4GB/s transfer capability. PCI-e II provides 8GB/s transfer capability.None of our Vcards even remotely need (PCI-e 8 lanes) 2GB/s of buss capacity now . . . and they want us to buy 8GB/s? Absolutely!With that rig, you might be better off to stick with a strong AGP8X card.

Thanks Sam,I faintly remembered your info but was quite unsure. I agree that we are specification happy and also in search of a few bragging rights. My objective has always been to get a video card at just less than $100. My old ATI 9800SE 128mb gives me over 40fps with most sliders to the right in FS9. In FSX it is just adequate with modest slider settings. This usually means pick one - full clouds, autogen, or AI. No combos.So off to Price Watch, Ebay, and Tom's Hardware to seek out the next $100 step up.e4400 clocked to 2.7ghz.Regards,Dick BoleyA PC, an LCD, speakers, CH yoke
