Recomendations for A Graphics card that will support 4 monitors

[Johnrmclean]

Recently I bought a new computer from HP. I talked to the sales rep at HP direct and told him I needed a machine with a graphics card that would support 4 monitors and that I would be using it to view stock charts and trade the market. He went through the specifications and hardware on line with me. In the end he did not know what he was doing and sold me a machine that would only support 2 monitors and with only a 300W power supply. Subsequently I went to Micro Center and told the sales rep I need to support and power 4 monitors. He sold me a 750w Corasir power supply and an XFX Radeon HD 7750 graphics card. I installed both just to find out this card will only support 3 monitors. Is every body in this industry this incompetent? Now I need to find a reasonably priced graphics card to replace the new card that will support 4 monitors . The mother board will only support a single card . Can someone recommend a specific product and model number that will fix this mess?
Thanks much.
John

Where it comes to buying computer components you never talk to sales representatives. Most of the time they have no ide what they're doing and they'll sell you the most expensive thing they have. For examples why in the world would you need 750w for a 7750? A cx430 would do just fine. Return the components if you can and get the following:

Visiontek 900345 radeon 6570

Corsair cx430

Sorry for not posting links but my device is being stupid and not letting me paste anything.
The vid card is good for doing office wor but be aware that it's not made for gaming.
