it is an xfx 4890 1gb.Desecrator said:^Performance wise, the 4890 wins hands down although it may not support Dx11 although it isn't a big deal. The power consumption of the 5770 would be lesser and so would be the thermal footprint.
What make is the 4890? How many years of warranty remaining? IINM a new 4890 costs about 11k today. So take into account all these factors before you take the plunge.
You shouldn't have problems playing it ont he 40 incher either way. And yeah your new PSU can take that without breaking a sweat.
