Those Sony's switch 1080p but probably don't upconvert to 1080p. But the upconversion part doesn't really matter. Your set (+ any future fixed pixel display you get) already has internal circuitry that converts/upconverts everything to its native resolution. It's quite unlikely that any current receiver would have significantly better scaling performance. Also, since you have a 1366x768 panel, the set has to rescale the receiver output anyway, which is likely more damaging than a single scaling operation.
Also upconversion doesn't really "upgrade resolution". It doesn't make anything sharper, and on your set you are already watching the result of an upconversion. You are always stuck with the limitations of the source material. It's just a matter of which deinterlacer/scaler circuitry does a better job of translating the source to the native resolution of the display, and the differences will be small. Don't buy into any marketing garbage about upconversion making things "near HD quality". There's no substitute for actual HD sources.
Until some of the newer fancier video processing chips get into the receivers (that might perform better than a given TV's), upconversion is really only a convenience feature, so that you can run only one video line to the display, and switch everything just using the receiver, instead of having to switch both receiver and TV input But in my view a better solution would be a good universal remote to accomplish that automatically, running an extra cable or two shouldn't be a big deal.
