Change to HD6850, the price is about 800, which is about the same as 7770, the performance is better, and the power consumption is also higher. 7770 and 650 are the same level, and they are almost the same for each other. In fact, the graphics card you come with is enough to play general 3D games, and you can use it if you don't pursue the effect too much.

350w is too low = = change the power supply, the high point of the graphics card can't be brought, change to 450 -500 is safer.

It must be Lanbao 7770, and the brand is better than Radium. 650 doesn't need to be considered, not even 7750, let alone 7770.

At least HD7850 and graphics cards below 7850 are sorry i5 3470

The 7850 seems to be 125w and should work.

At the same level, the performance is not much worse. Just look at that salesperson mm is beautiful!
