need new wifi router or go powerline

ok so in my house im running a netgear wgr614 wireless router. my GF uses the wireless for her laptop, which its fine for, although it does drop connection at times and can be noticeably slow, but its fine for what she needs it for. I on the other hand got a PS3 this christmas and the wireless connection to it is terrible, ive seen anywhere from 56%, the high, to about 27 percent. needless to say it would probably be terrible for gaming and im very afraid to run an update on it, for fear of the connection dropping in the middle of it or the file getting corrupted, thus bricking my ps3. ive been contemplating powerline networking options, either the netgear 200mbps unit or the linksys 200mbps. Im aware that they will never reach those speeds but I would be very satisfied with 80mbps. should I try the powerline option or is there a better wireless router out there that can offer me the speed and stability I desire??
