AMD vs Intel Xfire

[matt_desu]

I'm looking for a difference in performance between AMD 6000+ & Intel e8400 on a Xfire hd4850 system.

So far for the Intel system I was looking at the Asus P5Q Pro
The Intel CPU MB combo would cost roughly £200

The AMD combo would cost about £120-140
Not sure what MB for the AMD system though.

I'll be getting the 2nd GPU later on.
I'm also on a tight budget (student )

So any ideas on the difference in performance here, and is it really worth the extra £60-80
And any recommendations on a AMD xfire board?
Links to other threads or charts would be awesome.

Thanks

e8400 is WAY better for an xfire system. its way betetr period

 

[matt_desu]

But is it £80s better?
Also considering that it's got alot to do with GPU over CPU when it comes to games.

not exactly.

the 6000+ could possibly be a bottleneck for a single 4850, so when you throw that into xfire, you wont get the best out of it.

its certainly worth the 80.

if you look for the 8400, 131 fps, while a AMD quad core is way below that.

and an amd quad core is a lot better than a 6000+

I have to agree, if you're looking for top performance with a crossfire system, go with the E8400. Here's another chart about CPU scaling with a HD4870x2

A 6000+ is not a bottleneck for a 4850....

However the E8400 is the better buy, by far.

i didnt say it WAS, i said it could possibly be

Tats too much. Get the 6000+. On another thought i would get the 5400+BE and overclock the hell outta it. And intel boards, besides the x38/48, do xfire @ x8 x8, Amd ones can do x16 x16. if u go amd i would get something like this board http://www.newegg.com/Product/Product.aspx?Item=N82E16813128075 . gawd! 80 pounds is alot of money.

+1

had a 5000+ black edition OC'd to 6000 speeds, in UT3 while in a heavy firefight or large map, fps dips to like 30

same map, same heavy firefights with teh e8400 (@ stock 3ghz) stays at 50
with OC @ 3.8, stays at around 60

and this was with two diff gfx cards

so yes the cpu isnt just the gfx card's b**tch, it runs the show here

 

[wahdangun]

i think you should buy phenom x3 8750 black edition and oc it to 3,4 ghz(it's priced @ $134) + amd 790fx with sb 750

 

[zenmaster]

If you are worried about the cost, you could get an E5200 and it would both cost less than the X2-6000 and still faster.

Although I reckon the bottle-necking for my SLi'd GTXs is negligible with my 6000+.
In 3DMark perhaps, but certainly not in the real world.

You should not use that p45 motherboard for cf, it bottlenecks due to pcie throttling back to 8x in cf mode.

Consider an x38/48 board instead.

this is totally false, I had an x2 6000+ that out performed my 9600BE phenom all day long. clock for clock the x2 6000+ wins esp with the slight overclock to 3.2ghz. When I went to phenom i also had a 790fx board also. overall I lost 1000pts in 3dmark06. May games played like crap on the phenom, and on the x2 it was much better, signifcantly higher FPS.

the sb750 is nice, but id like to see facts before you say you can bump it to 3 or 4ghz. I call BS on this.

Exactly, I would suggest the x38 or x48. I have an x48 with 2 pcie 2.0 slots at full 16x bandwidth. You will be happy and for processor go with the e8400 or the q6600. you wont be disappointed. that's a guarantee.
