The gts 250 low profile is better than the 5570 (since it compares to the gt 240 which is better, the gts low profile has more stream processor but slower clock rates), except it's so big it's hard to call a low profile.
(just like the ms low profile 5670, it's low but it sure is long, and fat)
the msi low profile 5670 doesnt look fat or long to me. dimensions of it are, 195*69*34 mm which is longer and fatter then the 5570 but would fit in most pcs fine. the gts250 low profile is longer then the 5670 and double the width. its pretty much a dual slot card like the 5750 low profile.
Thanks for the info, I searched for the gt 420 earlier in the week and though I found info on it I couldn't find physical dimensions, thanks. It's comparison to the 5570 is up for debate, but if it compares to the gt 240 (it has half the processors but they and the memory -all 2gb- are clocked slightly higher) even if it's a good deal less. It will compete with the 5570. Either way the gt240 will probably be the better deal.
As for that gts 450 I saw it earlier and got all excited, but then it turns out it's about .5 inches too long. Oh well (it also uses a little more power than I would like).
I think I'll just wait until a good card comes out, or just do the build and use the IGP until it does.
well theres the 6000 series coming soon. lets see how much of a performance increase the 6570 (if its called that) has over the 5570. i also wonder if ati will stick with the low profile design. it might use even less power and give better performance, perfect card for htpc.
