Forsa is fine just don't expect it to be EVGA or Asus quality. They're a relatively silent graphics solution brand (founded in Hong Kong) which has been around for quite some time (since 1998). They do alot of OEM supplies and their cards mostly use reference coolers. Performance is identical to the reference units.
Similar to Leadtek, these will be the cheapest solutions you can get and do the job just fine. Just don't expect much overclocking, their components aren't as "cherry-picked". Volt-modding? Not recommended.
Had Forsa's Geforce 6xxxx series GPUs back then and they do the job just fine.
