hello, i recently build a pc, it has in it a amd phenom II x4 BE 955 on a biostar TA880GB+ motherboard with built in graphics AMD880G (RadeonHD4250) im wondering if an upgrade to a HIS Radeon 6870 is suficiant enough for gaming. im looking to spend around $200$ any sugestions?

The 4250 is an integrated chip meant to be cheap. The 6870 would be a fantastic choice to go with; The 6870 has 28x as many cores as the 4250. 1120 vs 40. You will be able to max most games at 1080p, with the exception of a few such as crysis and metro 2033.

The 6870 is a good card although i would personally recommend a gtx 560 ti just because of the over-clocking headroom in those.

A Radeon HD 6870 has a maximum load board power of 151 Watts. This means the graphics card itself will draw up to 12.6 Amps from the power supply unit's +12 Volt rails.

For a single Radeon HD 6870 graphics card system AMD recommends a power supply with 500 Watts or greater with a minimum +12 Volt current rating of 24 Amps and with at least two 6-pin PCI Express supplementary power connectors.

Is your power supply unit's combined +12 Volt rails current rating at least 24 Amps or greater?

A GeForce GTX 560 Ti requires at least 30 Amps or greater the power supply unit's combined +12 Volt rails.

The PSU is 750 WATT, I could not find any specs on the current rating at the rails. The only info in the motherboard manuel says that a suitable graphics card should support hybrid crossfirex technology.

If you post the make and model number of the power supply unit we might be able to determine its specifications.

SUNBEAMTECH PSU-ECO750-US-BL



No specification of the maximum wattage for the combined +12 Volt rails or even the combined +3.3 Volt & +5 Volt rails tells me that SUNBEAMTECH is pulling some kind of shenanigans with the specifications.

Calculations using the values on the label would indicate that the power supply would be able to provide 943.6 Watts. That just isn't possible as the label shows 750 Watts as the maximum. You cannot draw 60 Amps from the combined +12 Volt rails.
