yup thats right its the biggest case in 780 series gt 9800 was one lot wide so it fit this card i 2 slot wide and only 1 of them is pci express 2.0 not the other one will it fit same question for gtx 750 ti msi dual fan tooo????????????
You have the right to be careful. Dual slot is not going to fit in PCIE x16 slot without modifications.
First of all. What are you trying to fit, GTX 550TI as you stated in first post or GTX 750TI as you point it at your last post.
In any case please provide links to card you own (or at least exact model number). If you don't own that card, what is your budget and preferences. If you can provide 9800 model, which fits, that would be great, so we can guesstimate fit dimensions.
Next, please identify your PC from 2 pictures below - I am confused with the size of CPU heatsink with shroud assembly, both are listed as your model, but they look different.
Model A.
Model B
In any case, this is view from the back.
Do you have Dremel tool, or can you borrow it from someone.
You might have to cut one more slot opening to fit dual card.
