A) don't get that PSU, get a PSU with 450W-550W and 20A or more on the +12v rail
B) don't get Crucial RAM, if your planning on performance OC'ing or any tweaking grab something in a simmilar price range from OCZ or Corsair's XMS line
C) nVidia is supposed to launch it's new GeForce 7 series at the end of June (supposed to be June 22nd, but could get moved, but the 22nd is the most recent date i've found for it) and the thing will absolutly kill, so if you want more power you might consider that, and ATi is expected to launch it's new graphics card around the same time (R520, what it's called I have no clue, Radeon 11? or something new, but R520 is the name of the core design)
another thing, what is cooling the CPU? (is it including a fan?) also consider case air flow
aside from that, and the minor issue that R420/R480 doesn't support SM 3.0 (that means it can't play DirectX 9.0c) you are fine
if you want to buy a graphics card NOW, instead of waiting 4 months for nVidia/ATi to have their full lines out (nVidia will probably launch with the GTX, which is the highest end one, meaning it'll cost the most, and ATi will probably launch with the highest end one also, but to get down to the basic 7800's and basic ATi's will take a little longer (in theory))
but if you want it NOW, I would suggest an nVidia chip
while a 6800GT will be slightly slower, it will provide ShaderModel 3 support
yes, you can emulate SM3.0 on the X800XL, but the performance will be terrible (SM3.0 is found in all the latest games (HL2, FarCry, the upcoming U3 engine along with many others, Doom III and many others don't use it though) any current game will run amazingly fast on the X800XL
but considering that in about 6 months nVidia's new cards will be in full force
along with healthy competition from ATi (i know more about nVidia's new cards (like, their name) while I don't know so much about ATI's stuff, so I talk about nVidia's more because I know it about it more)
plus Intel and AMD are putting dual core
Intel should have chips on the market around July, and AMD is planning Q3-Q4 era from what i've read
that system would nontheless be fast, and I know you probably can't afford a dual core CPU (Which will retail for between $650 and $1100 US) and nVidia and ATi's new cards will probably be between $450 and $750 US on release, depending on the OEM, the retailer, and when your buying it
that system in no way would be bad
until you tried to run SM3.0
it can be software emulated, BUT the drawback is that it cuts performance down (a lot, if your emulating both Vertex and Pixel shader (one is easy/non-intenesive, and one is hard/mega-intensive, but i forget which is which, I think PS is the more intensive one, but i'm not entirely sure)
but with the exception of the RAM/graphics, which arne't bad, just not what i'd pick/reccomend/use
personally i'd say Corsair or OCZ (Muskin is also good)
and a 6800GT or 6800 Ultra depending on price
I'm building a computer and this just so happens to be the first one I have ever attempted to build. I was hoping someone could check this out and assure me that it is all compatible before I go ahead and start ordering parts.
MSI K8N Neo4 Platinum nForce4 Ultra (Socket 939) PCI-Express Motherboard
Seagate Barracuda 7200.7 Plus NCQ 80GB ST380817AS SATA 8MB Cache
HIS Excalibur ATI Radeon X800 XL ICEQII TURBO 256MB DDR3 TV-Out/DVI (PCI-Express)// Or something else if someone says so ...
Arctic Cooling T1 Silentium Silent Midi Tower Case - 350W Seasonic Silent PSU
AMD Athlon 64 3200+ 2.0GHz Socket 939, 512KB Winchester!
Crucial Ballistix PC-3200 BL6464Z402 512MB DDR
I think that's all I need I already have a DVD R/RW and I'll be buying another HDD later one with another stick of Crucial Ballistix PC-3200 (512)
So I think it's all set all these parts were found on www.overclockers.co.uk
Any advice?
