I have a system based on intel E2140, Biostar P35D2-A7, OCZ Reaper 2x1Gb Kit PC2 6400, ASUS GeForce 7300GT 128 Bit. Can I just replace the 7300GT with a GTX 5xx or 4xx GPU? What kind of PSU do I need? What's the best for GTX 580, is it x58 or p55?
Thanx for the advices..
If you can upgrade your GPU to a $500+ GPU I would say it is time to upgrade the rest of the system.
A good quality 550-600watt PSU for a single card.
X58 platform is the best on the market but we could argue whether it is worth the price premium over P55 platform based on usage.
I pretty much agree. A 2180 isn't the best match for a GTX580. I would argue you'd have a better experience spending that $500 on an i3/i5 system and an GTX460 then you would popping that GTX580 in. Seeing as you have a P35 board you could even maybe get a better CPU and a 570 or 560 when they come out.
I would advise you to wait for the new CPU's from intel and the new motherboards. When you will be able to buy those then build a system. At list that is what i would do. If the new CPU's are not worthy then you can always make a P55 or X58 platform anyway.
The system you have you can keep for media play, movies music and other. Make it a media PC and connect it to your big TV if you have one. If you want a card with HDMI buy a 5550 or just a little above. That should be enough for blu ray and other media.
Microcenter sells Q9300's for $99, so if you can I would get one of those. OC it to at least 3.0GHz, buy 2GB more of ram, and a cheap 775 mobo that supports SLI. All of that should come out to about $200. Then with the money left over either buy a new PSU and a single GTX 460 (and buy a second one down the road) or keep your current psu and go for dual 460's. SLI GTX 460 is roughly equal to a GTX 580. All of this should come out to $500-550.
core 2 quad is better than getting i3/i5.becuz its quad core and you wont see much difference than i5.even q8200 will be enough,get that.gtx 460 will be enough for gaming,you should only get sli when you get bore with one gtx 460.
