Incase any1 was wondering for PC gaming with the 5gb 21.6mbps black modem, i played 2nyt, my downlad speeds maxed at like 1.8mpbs download and like 1.2mbps upload.. I called Cell C told them that my speeds were very slow, they say a tech will come test the signal and adjust some base signal to get better speeds. so holding thumbs..
Ok onto the game part of BLACK OPS online play... If u take into consideration that I have the "fastest modem" and its running at fairly low speeds, what i say below will only be better if u having better speeds than me..
I started playing at about 8pm just finished now, 11:20pm played non stop, my ping hovered at about 80ms (i am in East London incase you wondering) didnt have any big lag spikes was very smooth... (even at low speeds) BANDWIDTH USED, to be exact adding the upload and download, used 88.78mbs....
All things considered when my speeds increase (hopefully soon) should run very very smooth.... Just for those guys wondering about PC and getting the dongle for black ops, from my side thumbs half way till my speed gets sorted then full thumbs up
