ok guys so i have decided to maybe jump onto some 750Ti's and build a dedicated rig.
i have a few systems kicking around, so would just need GPU's and risers, as ive seen many people using risers i need a bit of help.
So my spare i5 2500K has 3 PCI-E 2.0 x1 slots which im looking to use for powered risers, and 3 750Ti's
ive seen a lot of you guys having trouble with risers, bandwidth issues etc.
so what would you all say is a minimum in relation to;
1) PCI-E version (1.1, 2.0, 3.0)
2) CPU power needed to run 3 cards, ive seen dual cores with 4 i believe?
3) What algo's would you consider running, and expect to run properly on PCI-E 2.0 x1 slots?
4) Is there enough performance difference between the 750 and the 750TI to warrant an extra £20?
And if PCI-E 2.0 x1 is fast enough,
would you get one of these motherboards and just get a newer cpu? leaving a bit of headroom for another 2 gpu's
