first see https://hashcat.net/forum/thread-7717.html ,your kind of attack is considered to be outdated (mode 2500)
second, try using options -D 1,2 -O
this will tell hashcat to use CPU and GPU together with optimized kernel
third, hashrate depends on hashmode and attack, you can use
hashcat -D 1,2 -b -m 2500
to see your "very maximum speed"
example output
Speed.#1.........: 95898 H/s (45.44ms) @ Accel:8 Loops:512 Thr:1024 Vec:1
Speed.#2.........: 123.9 kH/s (46.01ms) @ Accel:64 Loops:64 Thr:1024 Vec:1
Speed.#5.........: 4776 H/s (71.94ms) @ Accel:128 Loops:512 Thr:1 Vec:4
Speed.#6.........: 5099 H/s (65.56ms) @ Accel:128 Loops:512 Thr:1 Vec:4
Speed.#*.........: 229.7 kH/s
i think your rate is quite okay for this "old gpu"
