Windows 7: Need help on buying a new graphic card!!

Power

like I said an OEM base is not a good way to go the boards they use are not meant for gaming or overclocking and you have no way to adjust voltages on those boards

You are able to manipulate voltage of several components using your bios, however I would strongly caution against it. Your questions indicate an interest but I don't beleive you posess the skill level and the understanding of what the consequences will be. I think what you are asking is can you overclock your processor, again you must possess a basic understanding of processor speeds and the reasons for either O/C or under clock. Gamers have a high understanding and have a need to overclock their processors to enhance the performance demands of their systems to get optimal performance. Your initial inquiry concerning graphics cards leads me to suspect that you are a fledgling gamer. So power demand is crucial for you to pursue your gaming goals.

AMPS

like i said in an earlier post don't forget about Amps it's not just all about the watts I stated earlier I use 25 amps on the +12 volt rail as a minimal starting point for a basic computer if you plan on having a high end computer then you would want a lot more but like I said you can get a pretty nice Corsair power supply for a decent price or PC Power and cooling never try to get by with a minimal power supply you risk damage to your whole system

watts

is there any other possible way to look at your watts or how much power does ur cpu has, becuase am having a difficult time lifting the top part off , and i changed my mind to buy a ATI Radeon 5770 since everyone is persuading me to go with the 5000's series how much watts do i need for that?

hm... if you go get a good 500 or 600 watt psu you'll be covered look at brands like corsair, ultra, pc power and cooling, antec, and thermaltake and modular is nice but its up to you if you want that option or not... the 5770 is a great card, and yes you can't overclock with a prebuilt system, but since you are just upgrading graphics now you will be fine with a new psu and card, and later on think about building a new computer

Read this: PC Power Consumption: How Many Watts Do We Need? - X-bit labs

Here's a tiered list, albeit from last year, that should get you headed in the right direction: Official XS Power Supply Ranking Phase I - XtremeSystems Forums

As has been stated before, do not devote too much attention to overall wattage, because that's going to differ from PSU to PSU, and more importantly, overall wattage is meaningless when it comes to powering a high end graphics card. You'll just give yourself a headache comparing wattage; psu's have different efficiency ratings, some are cleaner than others, etc etc etc...

What you want is a PSU with really stable rails. Most of the PSU that have been recommended in this thread will deliver, but again, some are better than others (refer to link 2).

It's all about the amps. Period. Get one with high amperage on the +12 volt rail and much of your concerns will evaporate.

To summarize: a lot of guys have already done the guinea pig work of figuring out what's good and what's not. Hit up link 2.

agreed......

IMO always buy a larger PSU than you think you need, invariably its one of the longest lasting components in a machine & if you buy good quality now it'll serve you for your future builds & any upgrades that may take your fancy.

i'll tell you about a GREAT PSU i picked up a year ago.......

Xclio 850w

what a great unit this is from an underdog company, this is their top end unit, superior build quality......

this has a whopping 70A on the 12v rail , & its bloody cheap..

it also has more connections than you'd know what to do with..

1 x 4pin ATX 12V
8 x 4pin Molex
2 x 6pin PCI-E Power <
1 x 8pin CPU +12V
2 x 8pin PCI-E Power <
1 x FDD Power
8 x SATA Power

its only downside is the fact its not modular, but that hasn't really bothered me (might be a problem with a smaller case due to cable storage)

but on the whole you cant go wrong with one of these.

The 5770 will suffer with only a 128-bit memory bus. I'd choose between either a 4890 or a 5870. However, if you have a factory PSU I would upgrade that too or build a PC for gaming - your quad-core may bottleneck the graphics card.

If he buys some watercooling/very good aircooling he can overclock it to the standards of the power it needs to run freely with those graphic options.
That is if he wants to spend yet more money...

New quad cores and fancy water cooling... all for a relatively minor upgrade? Let's slow down.

His Q6600 may be the system's bottleneck, but only in the sense that it's the slowest component should he opt for a 5870. That's a bit different that suggesting his core will bottleneck the card; that games will be choppy because the card has to wait for the core.

For some reason I doubt that will be an issue.
