...and there's one of the great tricks computer builders use to save money: The GTX 760 (OEM version) is a less powerful card than the GTX 760 (retail version), but has the same name. That computer has the former, which is 1896 GFLOPS vs 2257 of the retail card. In this case you can tell by the ram, the OEM version is available in 1.5 GB and 3 GB, the retail one in 2 GB and 4 GB (yes this means the 2 GB card is better than the 3 GB one). This is one of the advantages of looking at the wikipedia listing, benchmark tests normally only test retail cards so you'd get an inaccurately high impression.
Thankfully the difference in this case* isn't massive, only 16% less powerful, but I thought I should point it out.
*(unlike the GT 730, where the "128-bit DDR3" version is 268.8 GFLOPS vs 692.7 for the "64-bit DDR3" and "GDDR5" versions, which is less than half as powerful but named the same for no clear reason. They're all retail cards as well, it's not an OEM vs retail difference in that case.)
After all that... Yes that's a very nice PC.

Might be relevant?
Well, in that video, the card certainly seems to run just fine, although it's obviously not using any shader packs or anything like that.
In any case, the GTX 760 (any version) seems to be a lot more powerful than the GT640. The real question is, is it enough of a difference that it's worth paying almost 50% more for it (bearing in mind that this will be a difference of at least one, possibly two months of work in order to afford it)? Will the cheaper one run Minecraft with high graphics settings and a shader pack? If it will, I may go with that one for now, and save up for a better card in the future, since that seems to be the only major difference between the two machines. I mean, is that stronger video card alone worth another half a month's salary, all by itself? And do I actually *need* it to do what I want to do?
EDIT: Actually, I found a video for that.
https://www.youtube.com/watch?v=UYGTLF_7EKgIt seems it will run, although it's really just at the limit with a good shader pack. I could use a "lite" shader pack and I imagine it will work fine. This would allow me to get the computer at least a month or two sooner, and during that time I can actually be using it and enjoying it, and later on I can always save up for a new video card if I decide I really need it to be that fancy.
Thoughts?
