8700MGT is a midrange laptop card,if u dont want to game much,go for it.
In Laptops, unless you are aiming for ungodly prices, the best you can get is a 8600GT or a HD3650. Luckily i found a Toshiba with 512 GDDR3 dedicated for my brother. Not bad, but even so, it wasn't a cheap laptop. Pretty good all around, but GPU side, i wished i could have found him better.
Laptops take their sweet time updating, so if you are going to wait for a "revision" of the GPUs, i advice that you wait seated.
