so... I went out and bought
2 Gainward GTX 560 ti (2GB) "Phantom" - with apparently a too large cooler.
and I bought a Gigabyte GA-Z68X-UD7-B3
and to my surprise the two cards wont fit next to each other in the two 16x slots
and in the process of finding out i of course unpacked one of the cards breaking 2 "box sticker seals"
- the motherboard wasn't that hard to open i would probably have no problem returning that (in case i would need that)
- so what are my options
my own best is to try to return both cards - and replace them with 2 of these: EVGA GTX 560 Ti (2Gb)
these are like 10% more expensive and this might push the retailer to say "ok" even if i broke the "sticker seal" on one of the boxes
but if i cant return it - then whats the best solution ? new mobo new coolers or a third option?
