New SB build or just upgrade GFX?

Hi,

Been looking at Sandy Bridge and seeing how good it is and its making me want to get a new system.

But to be honest ive got a Q6600, 8GB DDR2 ram and a 9500GT and i just think i can hold out until that Sandy-E or Ivy Bridge comes out in a years time for a new machine. I want to 'double' my specs if i buy, so would want 8/16 cores and 16GB ram if its needed, but DDR3 is faster so 8GB of that might be sufficient.

The problem is my graphics card. i was using Pyrit which uses Cuda and noticed my card only has 32 cuda cores, im not sure if another name for it is stream processors? Whereas a top of the range GTX 580 has 512 of these Cuda cores.

After having a look today i think the GTX 560 and 470 were my primary choices but the power supply in my pc is quite low. A lot of the reviews said the 470 was terrible for power and heat, plus Nvidia state it needs 550W.

It says on the box of my PSU its 480W but my old one was 750W but that made a horrible noise at boot and got replaced. I still do have that one as a spare but havent figured out if its fixable yet. If i can fix it, i would put it back in my machine.


So my requirements are as below:

1. Have a decent ammount of Cuda Cores for pyrit processing.

2. Play recent games at a decent level, high/medium is ok

3. Have 2/3 outputs for displays, but the displays are really 2 tv's and a monitor, so both tv's have HDMI and VGA but no DVI. Not sure if you can get DVI to HDMI adaptors? i would want all three screens usable for the PC.
If its going to cost to much, i will be ok with 2 monitors like i use now.

4. Cost the most about £220 for a GFX card, £600 for a new build.

5. Preferble Nvidia, unless the ATI card is proven to work with Pyrit without to much hassle.

6. Motherboard is ASUS P5N-E SLI
on the cd and on a review it says it suited for Nvidia which i guess is for SLI but does that mean i cant get ATI cards?

Also on the Motherboard. question, can i keep my old 9500gt card just display output purposes? Im not sure if there is enough slots for another GFX if its not SLI?

So go for a GTX 560 or try and get £100 for what ive got and do an upgrade to SB?
That Intel medium build looks like a good starting poing if i could knock a few £'s off it on the forums.

Thanks.
 
Just upgrade the graphics card, by using a GTX460.

and putting the 9500gt in the second slot for a third diplay output.

A GTX460 768mb is approximately £120 and has loads of CUDA cores for speeding up apps that can use it.

your spec is still very good, do you have a SSD?

Use your current card for physx/ display out. Id get a 560 or the 460. I would wait until the full SB range is out. I am waiting for ivy bridge for my next upgrade i would reccommend you do the same. 560 has more cuda cores

I was thinking of a GTX460 but was going to wait for the GTX560 to see if it was worth it, or the prices of the GTX460 would plumit.

Thing with 460 is i think its old now and wont support DirectX 11 well? or is that wrong?

Im not sure that MB has enough space for 2 displays thats why i posted its model to make sure, its defo got SLI but not sure about two slots for totally differnt cards.

Is the 768MB 192bit interface good enough or should i go for the 1GB 256bit version? The GTX460 would power the main monitor via DVI which is maxxed at 1440x900 my 2nd display has the same resolution but can get higher even though thats only connected via VGA?
But as the GTX460 doesnt have VGA thats the display that will be run via the 9500GT
The tv and 2nd display are full HD but the 2nd display will be powered by VGA by the 9500GT so doesnt really matter there.

I dont have an SSD drive, didnt think would be any point because i dont have Sata 6GB only 3GB. Plus it doesnt support AHCI, but a guy called Bunyan in another thread has the same MB as me and said it runs great.

Think i would lose 70MB/s read by not having AHCI but would still be rapid i guess. Drive ive got at the minute is terrible! honestly takes 2 minutes to boot and ive only got 43 processes at startup. Shutdown is fine takes 15 seconds but bootup....

Drive is hitachi HDP725050GLA. OP gets 90MB/s read with that and 250 MB/s read with the SSD but Bunyan gets over 250MB/s with his SSD on my MB.

GTX 560 has 384 Cuda Cores and GTX 460 has 336 Cuda cores. Might be + 1000 items per second difference in Pyrit, as my current 9500gt is 32 cores and that does 1000 items a second. Im not totally sure on that though.

Motherboard Expansion slots:

2 x PCIe x16 , Single VGA mode: x16 (Default), SLI mode: x8, x8
1 x PCIe x1
2 x PCI 2.2

Does that single VGA mode mean i can only use VGA to get x16? Not quite sure what those numbers mean if someone could explain?
