I have been using my dual core lappie since I came into VR. I do intend on upgrading, however, to at least a quad with new graphics that come standard nowadays, and more memory...
I also run win7 but will be fine with 8 when I upgrade.
I also hypergate all over the meta, and tbh, the stability of a grid run type OS using the HG works quite well for me as I often just HG in from other places to here now.
In other HG enabled grids, often people are connecting their own instances to a grid to use their asset and such storage, as well. So you get a mish mash of OS versions on all sorts of computers running them, which all adds up to a variety of issues hypergating outside of Kitely, and even coming in.
I kinda like this...lol
I also log in with graphics to medium and draw to whatever minimum the viewer allows. Then I increase it as the region starts loading for me, often turning around in a circle to have my viewer see the closer items, then go to like 100 or so to travel around. I expect my next computer will make this all much better, too.By prevailing over all obstacles and distractions, one may unfailingly arrive at his chosen goal or destination. --

But I won't be buying those expensive [to me also] types of computers, and don't see the need, for me, anyway.
Have fun!!
