Am i just screwed with hughesnet as far as upload speed?

i play chess on line a lot and have about a four second lag time with the clock, my download speeds are sufficient but was told the highest upload guaranteed is approx 300 kbps. Most say with online gaming the upload and download speeds should be approximately even....any suggestions?
Update: perhaps i should clarify: yahoo chess games have clock; when i make a move on MY computer screen, it takes approximately 2-4 seconds for the gameclock to register that move. This is clearly a case of upload speed isn't it or am i missing something?
