help troubleshooting mining issues (or my bad luck)

I am very new to mining (and cryptocurrency in general) and having some trouble getting ether after the initial setup. I have been mining with 2*R290 for a day now and still nothing shows up in my balance. So I would appreciate it very much if someone can tell me what I am doing wrong. Thanks in advance.

I am using ethminer and geth with following options:

geth --rpccorsdomain "localhost" 2>> geth_log &
ethminer -G >>gpu_log

The ethminer log shows that my gpus are diligently working.

However the geth log is suspicious, it often shows "imported 256 block(s)". My understanding is that if I have caught up with the network, it should be showing something like "imported 1 block(s)". However, I think I do downloaded the blockchain db and if I just run "geth", it will show something like "imported 256 block(s)", "imported 17 block(s)", "imported 0 block(s)", "imported 1 block(s)", that is, not always 256 blocks. I am wondering if it still means I have not synced with the network or I have a particularly low-performance CPU (celeron 2.7G) so the verification time is long? I really need some help to understand this issue.

Attached are snippets of ethminer log and geth log.
