Its a gigabyte board with PCx16 V1.8. Acer does not make mobos.

TherealYeno allready found it, in my cpuid stood that it was an acer, but it was incorrect, will it run on 1.8?

http://www.alternate.nl/html/product/Gr ... OC/579845/? or will this fit? is it good? and it has PCI 2.0

[reaper15058832]

Both will fit. It will just be bottlenecked ie run slower because of you mobo. I like that MSI, it is OC'd!

that doesn't mather, but could i play mw 3 on high settings even with the bottleneck?

[reaper15058832]

MW3 I think so.I am not sure on the % performance drop from 2.0 (incl 2.1) to 1.0 (incl 1.8 and all other versions of 1)....

[them16master]

bwah doesn't mather, medium is also fine for me

You can save up for a new mobo over the next few months. They aren't that expensive.But you'll need to save some money first

Looked around a bit and In most cases it seems that a PCI-e 2.1 card will work in a PCI-e 1.x slot. However, there have been cases where it doesn't work at all. Look for a BIOS update for your MoBo. If there is one then look to see if it mentions anything about PCI-e 2.1. If there is no updated BIOS or no mention of PCI-e 2.1 support, then the only way to find out is to actually buy the card and install it. About performance drop, its marginal (~5%) or nonexistant. There is no way of knowing for certain but it should work...

If i may reccomend postponing the purchase untill you have enough for both GPU and a decent MoBo.

[them16master]

how much costs a decent mobo? I don't want an expensive one, just cheaper but decent.

I think buying a new mobo for an old socket is a bad move unless you can get one cheap. Otherwise save up and get a new mobo with a new cpu like a Sandy bridge or Phenom II.
