PCI Express 2.0 question

[moomoomoo]

Really tempted by the 280gtx, however my mobo doesnt support pci-e 2.0. Will this effect the performance i will get from the card, if so by how much.

My current mobo is a asus p5n32-e sli plus, was hoping to get another year out of it before upgrading.

Thanks.

I thought there still wasn't any cards that had out performed pcie1

So your saying normal pci-e is faster then the 2.0 version ?

I assumed pci-e 2.0 been newer it would be better and faster. I have looked around the web and not got any answers yet. I read that pci-e 2.0 was faster at sending data and such so again i assumed it was was faster and better.

I am confused

Well people are posting results that a 4850 is limited on a 8x pci-e = 16 x pci-e 1.0 bandwidth so a more powerful card such as a GTX280 will be even more crippled.

CRIPPLED, dont like the sound of that

It is. He wasn't saying that.

A pci-e 1 16x slot has 2.5Gb of bandwidth. a 16x pci-e 2 slot has double the bandwidth of 5gb/sec.

He was saying that he wasn't aware of a card using all the bandwidth of a pci-e 1 slot yet.

Ohhhh ok, i see now. So a 280 gtx would use all the bandwith of a pci-e 1 slot ? thats why the extra bandwidth of the 2.0 slot is needed i guess.

So how much performance would i lose using the card in the pci-e 1 slot. Would a a 260gtx be better suited to a pci-e 1 slot.

Sorry for all the questions i just wanna be sure what i am getting before i folk out the money I really dont wanna have to upgrade my motherboard as well as the graphics card. I think my mobo is pretty decent and as i said i want another year out of it !

you have been helpful i feel more clued up now i currently have a asus 8800 gts 640 mb so as forsted nipples has said even if its limted its still a lot better then what i have. However when your paying 400 quid plus for a card you dont ant it to be limited.

What i think i am gonna now do is sell some of my old parts, (i have just about enough to build a pc) think i will get a 260 gtx since my monitor only goes up to the 1620 res i think a 280 will be wasted on me anyways. The money i will save i can put towards a new mobo, the in time maybe get another 260 gtx.

Hmmmm unless it turns out i dont need a new mobo after all.

Arrrrh This uprading lark is stressfull.

Seems like i am not the only confused one

I have no clue if i have pci-e 1.1 or 1.0, i will try find out.

I have another question.

The 9800 gx2 out performs the 260 in benchmarks, the gx2 is bascily 2 graphics cards in one slot so is more powerfull then a single 260 gtx. Surely the gx2 would use more bandwidth then the single 260 gtx. Yet theres no mention of the gx2 been compatible with the pci-e 2.0, so what i am saying if a gx2, a dual graphics card in one slot doesnt need the extra bandwidth of pci-e 2.0 why does a 260 gtx?

Hmmmm?

I am on the n force 6 chipset, its says i have 2xPCI-E slots at full x16 speed in my manual, will i be fine ?
Says nothing about 1.1

 

[moomoomoo]

still dont know if my asus p5n32-e sli plus , nforce 6 chipset will be it ok, can any one tell meeeee.

I took the plunge and got a 260 gtx i felt it was better vaule for the res i game at. It runs all my games, cod 4, tf 2 , grid , mass effect, ut3, all on full settings, aa and so one at 1680 res get 60+ fps in all them games it drops slightly when theres a lot going on but nothing you notice when you havnt got a fps counter on.

But i hear the 260s use a lot less power then the 4870's and gtx 280 so i assume uses less bandwidth also.
