When you go to "Convert" for TGA>TX, you get a lot of options. I think usually people use R5G6B5 - 16bit (16bit color), which is a BMP style format with no quality loss and no compression.
The other options offer various levels of compression; you can try them and see which one gives a good result. I've been using DXT1 - 4x compressed for the new loading screens, for example.
You can tell the difference in that case, but the quality drop isn't too bad, so I think it's a small price to pay for a lot smaller download size.
