Want to crossfire a HD5770 - Motherboard Q

Hey.

So this is the spec I bought last year.

iT 1003 Black Gaming Case No Psu
500 GB Seagate ST3500418AS Barracud
4GB (2x2GB) Corsair Dominator DDR3
BCL Slimline Black Gaming Keyboard
LiteOn IHAS124-19 24x DVD±R, 8x DVD
MSI 770-G45, AMD 770, AM3, PCI-E 2.
750W Powercool PC750UM, Modular, 80
AMD Phenom II X6 1055T, Thuban, Sok
1GB XFX HD5770, PCI-E 2.0(x16), 480

Now in preparation for GW2 I was thinking about running another HD5770 in crossfire with the one I currently have. I know that my power supply is able to support this but I am not sure about the motherboard.

Let me explain. The motherboard has 2x pci-e x16 slots, one that runs with x16 speed and the other at 4x speed. Does this mean, due the the second slot only having a 4x speed, that crossfiring two HD5770s would be pointless?

Thanks

4x might very well be to slow, i would not recommend it. It will work but the scaling might suffer.

thanks.

regardless do you think that I will see a significant performance increase?

enough to run Gw2 on high maybe?

I you should hold of and wait for gw2 specs and next years graphics cards. Unless you find a 5770 dirt cheap it's not worth imo and you might just get more bang for the buck tossing out the 5770 you have for a next year card.

Even now the gtx560ti and HD6950 goes fairly cheap and might scale better.

Check prizes for both options and if you don't need it now then wait.

thank you, the 5770's are quite abit cheaper than they where when i first purchased mine.

i think im going to stick with what ive got atm, it feels only last week i bought it so don't really want to have to throw it away so soon.

i wonder how 2 of them in crossfire would run gw2 o.O

40-80% faster then one?

Nice

hopefully that will be more than enough. with one HD5770 i've been able to run rift on medium settings and current guild wars with constant 60 fps. (also wow with great fps, but it really dropped in the big cities at peak times)

I assume they won't make GW2 too graphically intense so that a larger majority of people can experience it fluently!

cheers for your help!

depending on the multi card support tho it can be slower then one.
It's safer to have just one faster card then two slower.

Also neither WoW or gw are demanding games i would expect those to be any problem. Your system is a little faster then the recommended spec for rift.
