e521 graphics card upgrade

I am in need for a graphics card which will be compatible with my dell e521 desktop pc. The main reason i am upgrading is because the computer currently has only 1 vga slot, and i am in need for 2 monitors connected to my pc. The PC runs on vista, and apparently has limited power supply. i do not want to upgrade my powersupply, so as long as i can have 2 monitors connected to my pc, i am pretty much happy. a gfx card ranging from £40-£70 is perfect. ould anyone recommend any graphic cards which meet my requirements?? thanks in advance.

here are the specs for my pc: http://support.dell.com/support/edocs/systems/dimE521/en/SM_EN/specs.htm#wp1052310

You need a PCI-E x16 card - as you have a normal sized case a full size card would be fine but your limiting factor as already identified is the power supply - the E521 has a 305W supply.
The problem with the system board is plugging a 16x graphics card into the expansion slot will disable the onboard graphics so you'll need a dual head card.
Depends on what you want to use it for but for most applications consider nVidia 9500GT or ATI 4650 based cards (or better) - the higher spec cards will require external power supply though.
Assuming you've not added anything else to the basic spec system you've 50-80W overhead to play with.

thanks for your help. would you think that the  ATI 4650  is an average size in terms of the size of the graphics card? i read apparently there is limited space in the dell case, even though there is 3 pci card slots available. i think it should be fine.. but would just need clarification if poss? does it look the norm in size?

☠ MASQ ☠Commented:
4650 cards vary with manufacturer. The biggest difference is in the position and height of the cooling fan. You need to remember that the fan on the card will be underneath when mounted. This means the PCI socket below will be useless. There's a small possibility that if the card is extended it could foul the IDE controller socket which is behind and slightly above the PCI-E x16 slot. On the BTX board the expansion slots were a bit of an after-thought the PCI-E x1 slot is right at the edge of the board and relies on there being space inside the case for it to overlap. Space is certainly an issue.

What do you need in terms of performance?  Games/CAD/basic office work?

my main purpose is for 2 monitors cos i play poker and i need to spread the tables across 2 screens to see my tables properly. if i could game, that would be nice, bt not a big deal.

How about something as simple as a second user nVidia 6800GT off eBay?

in terms of power, would the hd 4650 work with my pc? if so, i am going for this, cos i have done abit of research and i cannot find anywhere where it says it won't fit. i think i will be purchasing it from

would this be ok, forgetting the size of it?

You should be just about OK for power it will pull about 90W at rest and at absolute most 140W - You'll need a six pin power adaptor to come off a spare Molex connector on your PSU to power it though.

Even better - around 30W at rest rising to around 50w Max.
You should make sure the Dell PSU 12V rail is rated at 20A or better though as this one pulls its power though the motherboard
(Note the recommendation for a 350W PSU)

could you recommend a power supply i could get at a relevant cheapish price? i think i am just going to upgrade both the power and get the 7600.

You can also use a PCI video card which won't disable your on-board video.
Power consumption can be quite small that way.

PCI cards are also available in dual-head versions.

just for a bit of feedback - in the end i purchased geforce 7600. worked fine although when installing drivers from the cd was a bit of an issue, so downloaded it from nvidias website. thanks for ur help everyone.
