Hey all,

I have a Dell Studio 540 tower bought a while back and want to upgrade the graphics card so I can play some modern games at a decent resolution (1650x1050) with playable framerates... the 3650 just doesn't cut it. :kaola:

I'm thinking of going for the 5770, although I'll have to upgrade the PSU too as I've got the standard 350W currently installed. The system requirements for the 5770 states a 450 Watt or greater power supply with one 75W 6-pin PCI Express power connector is recommended so I've seen two that seem to be worth buying. I don't want to spend a whole lot on these upgrades since I'm building a new gaming PC from scratch.

The specs of my Dell:

Mainboard : Dell 0M017G
Chipset : Intel G43/G45
Processor : Intel Core 2 Duo E8400 @ 3000 MHz
Physical Memory : 3072 MB (3 x 1024 DDR2-SDRAM )
Video Card : ATI Radeon HD 3600 Series

Parts I'm looking to upgrade to:

GPU:

HIS HD 5770 1GB GDDR5 DVI HDMI Display Port Out PCI-E Graphics Card

PSU:

Be Quiet 530W Pure Power PSU - 120mm Fan Dual 12V Rails 5x SATA 2x PCI-E
OR
OCZ Stealth XStream 600W PSU - SLI Ready ATX2.2 12cm Fan

- Will these components be fully compatible with my current specs (seeing as it's a prebuilt Dell machine) and boost gaming performance?

- Is the 530W PSU enough or would it be safer to go with 600W?

- Would it be wise to intall another gig of RAM to increase total memory to 4GB and increase performance?

Thanks for any help!

You learn something new everyday, thanks. Also is the 400 watt corsair really a 500 watt? Cause my brother bought a 400 watt last November.
