Looks great value with good overclocking potential if you ever find it isn't fast enough for you
No mention of the brand\model of supplied PSU which would raise a question with me, but the 2 yr warranty should reassure you in that respect.
Also, for graphics & video work, the card is certainly not the fastest in the latest terms which will be the performance bottleneck* (and provide a very easy upgrade path at a later time)...but adding another 4gb and using the 64bit o/s's would go a long way to compensate anyway should you so choose.
*bottleneck - the video card is fairly quick, but the cpu can provide it with data faster than the card can process it in some cases. Should be plenty speedy all the same.
